Power Integrations, a leading manufacturer of high-voltage integrated circuits focused on energy-efficient power conversion, recently introduced the InnoSwitch3-Pro series of off-line flyback switching power ICs. These devices offer versatile output characteristics such as constant voltage (CV), constant current (CC), and constant power (CP) modes. The new IC delivers up to 65 W of output power with an impressive efficiency of 94% across a wide range of input voltages and load conditions.
One of the standout features is the ability to precisely control output voltage and current using a simple two-wire I2C interface. This allows for voltage steps as small as 10 mV and current steps of 50 mA, making it ideal for applications requiring fine-tuned power delivery. The InnoSwitch3-Pro works seamlessly with a microcontroller, enabling system CPUs to manage and monitor the power supply dynamically.
The device supports a broad array of fast-charging protocols, including USB Power Delivery (PD) 3.0 + PPS, Quick Charge 4/4+, AFC, VOOC, SCP, FCP, and others. It's suitable for a wide range of applications, from consumer battery chargers and dimmable LED ballasts to industrial power supplies with adjustable outputs.
In terms of design, the InnoSwitch3-Pro integrates a microprocessor VCC supply, eliminating the need for an external LDO to power the microcontroller. It also includes an n-channel MOSFET driver that can control the main power output. Additionally, the IC incorporates telemetry functions for monitoring bus voltage, current, and fault reporting, along with customizable protection features like over-temperature, input and output overvoltage/undervoltage, and short-circuit protection. This significantly reduces BOM components and simplifies power supply design.
Shyam Dujari, Director of Product Marketing at Power Integrations, highlighted the growing demand for programmable power solutions in the AC-DC market. He noted that the InnoSwitch3-Pro’s flexibility makes it particularly useful for designers working on small-batch production, allowing them to easily configure output specifications during manufacturing or installation.
The InnoSwitch3-Pro leverages Power Integrations’ advanced FluxLink™ technology, combined with synchronous rectification, quasi-resonant switching, and precise secondary-side feedback control. It is certified by CQC, UL, and TUV (EN60950) and safely isolates the primary and secondary sides of the power supply. The InSOP® 24D package offers a compact and efficient solution with enhanced creepage and clearance distances, improving reliability, surge immunity, and ESD protection.
The InnoSwitch3-Pro is ideal for a variety of applications, including smartphones, laptops, tablets, smart speakers, and other devices requiring controlled or adjustable output. Samples are now available for purchase, priced at $1.12 per unit for orders of 10,000 pieces.
