General Description

The iW1691 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 at heavy load to provide high efficiency along with a number of key built-in protection

Overview

iW1691 Digital PWM Current-Mode Controller for Quasi-Resonant.

Key Features

  • while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW1691 removes the need for secondary feedback circuitry 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.
