Datasheet Summary
Off-Line Digital Green-Mode Quasi-Resonant PWM Controller
1.0 Features
- - No-load power consumption < 30mW at 230VAC along with fast dynamic load response and short turn-on delay time in typical 12W pact adapter/charger applications
- - Tight constant-voltage and constant-current regulation across line and load range
- - Primary-side feedback eliminates opto-isolators and simplifies design
2.0 Description
The iW1699 is a high performance AC/DC power supply controller which uses digital control technology to build peak current mode PWM flyback power supplies. The device operates in quasi-resonant mode to provide high efficiency along with a number of key built-in protection...
