General Description

The iW1760B 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 quasiresonant mode to provide high efficiency along with a number of key built-in protection

Overview

iW1760B Off-Line Digital Green-Mode Quasi-Resonant PWM Controller 1.

Key Features

  • while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW1760B 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.
