IW1688 Product details

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.
