IW1688 - Low Power Off Line Digital PWM Controller

Description

The iW1688 is a high performance power supply controller which uses digital control technology to build sensorless peak current mode PWM flyback power supplies.

Features

  • Primary-side feedback eliminates opto-isolators and simplifies design Multi-mode operation for highest overall efficiency ±4% typical output voltage regulation No external compensation components required Complies with CEC/EPA no load power consumption and average efficiency regulations Built-in output constant-current control with foldback Low start-up current (8 µA typical) Built-in soft.
