Datasheet Summary
Off-Line Digital Green-Mode Quasi-Resonant PWM Controller
1 Description
The iW1699 is a high performance AC/DC power supply controller that uses digital control technology to build peak current mode PWM flyback power supplies. The device operates in quasi-resonant mode to provide high efficiency and key built-in protection Features while minimizing the external ponent count, simplifying EMI design and lowering the total bill of material cost. The iW1699 removes the need for a secondary feedback circuit while achieving excellent line and load regulation. It also eliminates the need for loop pensation ponents while maintaining stability over all operating conditions....
