iW1699 - Off-Line Digital Green-Mode Quasi-Resonant PWM Controller
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.
Features
while minimizing the external component 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 compensation components while maintaining stability over all operating conditions. Pulse-by-pulse waveform analysis allows for a loop response that is much faster than traditional solutions, resulting in improved dynamic load response.
