Overview

iW1699B Off-Line Digital Green-Mode Quasi-Resonant PWM Controller.

Key Features

while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW1699B removes the need for 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.
