General Description

The iW1706 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 directly drives a power BJT and operates in quasi-resonant mode to provide high efficiency along with a number of key built-in protection

Key Features

  • while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW1706 features a distinctive soft-start scheme, which allows for fast and yet smooth start-up with both small and large capacitive loads. The iW1706 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.
