Product details

Description

The iW1689 is a high performance AC/DC 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.
Very tight output voltage regulation.
No external compensation components required.
Complies with CEC/EPA/IEC no load power consumption and average efficiency regulations.
Built-in secondary constant-current control with primaryside feedback.
Low start-up current (8 µA typical).
Built-in soft s.
