iW3620 - Digital PWM Current-Mode Controller

Datasheet Summary

Description

The iW3620 is a high performance AC/DC offline LED driver which uses digital control technology to build peak current mode PWM flyback power supplies.

Features

  • Primary-side feedback eliminates opto-isolators and simplifies design.
  • Quasi-resonant operation for highest overall efficiency.
  • EZ-EMI ® design to easily meet global EMI standards.
  • Up to 130 kHz switching frequency enables small adapter size.
  • Very tight LED constant current regulation.
  • No external compensation components required.
  • Built-in output constant-current control with primary-side feedback for LED driver.
  • Low start-up current (10 µA typical).
