LT8302 - Micropower No-Opto Isolated Flyback Converter

Datasheet Summary

Description

The LT®8302/LT8302-3 is a monolithic micropower isolated flyback converter.

By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no third winding or opto-isolator for regulation.

Features

  • n 3V to 42V Input Voltage Range n 3.6A, 65V Internal DMOS Power Switch n Low Quiescent Current: n 106µA in Sleep Mode n 380µA in Active Mode n Quasi-Resonant Boundary Mode Operation at Heavy Load n Low Ripple Burst Mode® Operation at Light Load n Minimum Load < 0.5% (Typ) of Full Output n No Transformer Third Winding or Opto-Isolator Required for Output Voltage Regulation n Accurate EN/UVLO Threshold and Hysteresis n Internal Compensation and Soft-Start n Temperature Compensation for Output Diod.
