Power Integrations introduces T8 lamp ballast design efficiency over 91%

[High-tech LED] General Lighting LED driver IC company Power Integrations released a new 25 W LED T8 lamp ballast power supply reference design. The most striking feature of this design (DER-287) is its efficiency of over 91%, reaching industry-leading levels, while still meeting power factor (PF greater than 0.9) and harmonic distortion (EN61000-3-2 Class C). Commercial requirements.

The DER-287 is a single-stage converter designed with the LNK409EG, one of the LinkSwitch-PH family of LED driver ICs. Single-stage technology greatly extends product life by eliminating the need for optical isolators and large aluminum electrolytic capacitors used in traditional two-stage designs.

Power Integrations said that achieving high power conversion efficiency is as important as LED choice in improving the overall luminous efficiency of lighting fixtures. If a single-stage topology is not used, it is extremely difficult to achieve an efficiency of more than 88% in a cost-effective manner in a T8 tube with a small space. The efficiency of the design is easily over 91%.

In addition to a highly integrated monolithic design that integrates controller, driver and switching MOSFETs into one package simultaneously, Power Integrations' LinkSwitch-PH product line includes over-temperature protection and over-current protection. This means that only a few peripheral components are required to implement the design.

In addition, the LinkSwitch-PH LED driver IC meets the requirements of low THD or high PF for commercial and industrial lighting products, making the final design suitable for the global market.

2.0mm (0.079") Pitch Female Headers


2.00 mm pitch female sockets/headers are low-profile connectors designed for signal and low power PC board connections when space is at a premium. Options include through-hole, surface mount and can be customized for mixed technology, press-fit and pass-through terminations. The pins and blades are available in various sizes, counts, amperages, and plating.

The 2.0mm can accommodate a maximum current of 3A, with a 30 to 22 AWG wire size, and up to 40-positions. Antenk offers 2.0mm pitch female headers in either vertical or right-angle orientation at high quality and affordable China-quoted price that snuggly fits with the pins of a Male Header and acts as a receptacle.

The 2.0mm pitch female headers are commonly found in PC`s and are also made to work in Arduino boards, Arduino Pro and Arduino Mega with either single or double-row female headers, facilitating connections for programming and incorporation into other circuits. They have the perfect height for clearing the USB-B connector and great for stacking multiple shields.

Female header always called as [Header connector", Antenk provide widely range of header connector, from 2.54mm (.100″ inch) pitch to 1.0mm (.039″ inch) pitch. The number of pins (contacts) is from 2 to 40 pins per orw. There are three type: Straight (Dip Vertical), Right angle, SMT (surface mount).

Applications of 2.0mm Pitch Female Headers
LED applications
Arduino boards
Solar applications
Weighing systems

Air conditioner
Microwave oven
Washing machine
Water heater
Shower toilet
Automotive, Heavy Duty Military and Marine
For densely packed equipment requiring weight reduction and downsizing and for tough and harsh conditions.
Vehicle infotainment
Computer peripherals
Battery Connections
Battery connections rely on the ability of the current to pass reliable and solid current. This prevents overheating in the circuit and voltage drop.
Rechargeable battery packs
Battery balancers
Battery eliminator circuits
Medical Diagnostic and Monitoring equipment
Heart monitors



Mount Type: Through-hole vs Surface Mount
At one side of this female header is a series of pins which can either be mounted and soldered directly onto the surface of the PCB (SMT) or placed into drilled holes on the PCB (THM).

Through-Hole (Poke-In)
Best used for high-reliability products that require stronger connections between layers.
Aerospace and military products are most likely to require this type of mounting as these products experience extreme accelerations, collisions, or high temperatures.
Useful in test and prototyping applications that sometimes require manual adjustments and replacements.
2.0mm vertical single row female header, 2.0mm vertical dual row female header, 2.0mm right-angle single row female header and 2.0mm right-angle dual row female header are some examples of Antenk products with through-hole mount type.

The most common electronic hardware requirements are SMT.
Essential in PCB design and manufacturing, having improved the quality and performance of PCBs overall.
Cost of processing and handling is reduced.
SMT components can be mounted on both side of the board.
Ability to fit a high number of small components on a PCB has allowed for much denser, higher performing, and smaller PCBs.
2.0mm Right-angle Dual Row female header, 2.0mm SMT Single row female header and 2.0mm SMT Dual row female header are Antenk`s SMT female headers.

Soldering Temperature for 2.0mm Pitch Female Headers
Soldering SMT female connectors can be done at a maximum peak temperature of 260°C for maximum 60 seconds.

Orientation/Pin-Type: Vertical (Straight) and Right-Angle
2.0mm pitch female headers may be further classified into pin orientation as well, such as vertical or straight male header or right-angle female header.
Vertical or Straight Female Header Orientation
One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called "straight" or [vertical") or.

Right-Angle Female Header Orientation
Parallel to the board's surface (referred to as "right-angle" pins).
Each of these pin-types have different applications that fit with their specific configuration.

Pcb Connector Stacking
For 2.0mm pitch female headers, the orientation is either offered as vertical or right-angle, which are options. Elevated sockets/female headers can be available upon request.

Profile Above PCB
This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.

Elevated Sockets/Female Headers
Elevated Sockets aka Stacked sockets/receptacles or Mezzanine are simply stacked female headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.

Choosing this type of stacking configuration promotes the following benefits:
Connector Isolation - the contacts are shrouded preventing cable connection mishaps and good guidance for the mating header connectors.
For off-the-shelf wireless PCB module, stacking height is optimized with elevated sockets.
Offers superior strength and rigidity.
Polarisation prevents users from inverted insertion.

Single, Dual or Multiple Number of Rows
For a 2.0mm straight or vertical female header, the standard number of rows that Antenk offers ranges from 1 to 2 rows. However, customization can be available if 3, 4 or n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-40 pins while for dual row, the number contacts may vary from 2-80 pins.

Pin Material
The pins of the connector attached to the board have been designed with copper alloy. With customer`s demand the pins can be made gold plated.

Custom 2.0mm Pitch Female Headers
Customizable 2.0 mm pitch female headers are also available, making your manufacturing process way faster as the pins are already inserted in the headers, insulator height is made at the right size and the accurate pin length you require is followed.
Parts are made using semi-automated manufacturing processes that ensure both precision and delicacy in handling the headers before packaging on tape and reel.

Tape and Reel Packaging for SMT Components
Antenk's SMT headers are offered with customizable mating pin lengths, in which each series has multiple number of of circuits, summing up to a thousand individual part number combinations per connector series.
The tape and reel carrier strip ensures that the headers are packaged within accurately sized cavities for its height, width and depth, securing the headers from the environment and maintaining consistent position during transportation.
Antenk also offer a range of custom Tape and reel carrier strip packaging cavities.
