110V LED power supply design based on LT3795

MOS power IC full range

SMD LED

Overview:
Linear's LT3795 is a 110V LED controller with wide-spectrum frequency modulation. It can be used for constant voltage or constant current output. It is very suitable for driving LED. The internal 7.7V regulated power supply can drive an external N-channel power MOSFET with input voltage from 4.5V to 110V. , 3000:1 true color PWM dimming, constant voltage regulator ± 2%, programmable input current, adjustable frequency from 100kHz to 1MHz, mainly used in high power and high voltage LED, battery charger and precision current limiting voltage stability This article describes the main features of the LT3795, block diagrams, several application current and demo board schematics, test circuits and bill of materials.
