iW1699 - Dialog Semiconductor

iW1699 Off-Line Digital Green-Mode Quasi-Resonant PWM Controller

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 component count, simplifying EMI design and lowering the total bill .

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 for both one-time and repetitive load transients. The built-in power limit function enables optimiz.
