IW1699
Overview
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 features while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost.
- No-load power consumption < 30mW at 230VAC along with fast dynamic load response and short turn-on delay time in typical 12W compact adapter/charger applications *
- Tight constant-voltage and constant-current regulation across line and load range *
- Primary-side feedback eliminates opto-isolators and simplifies design
