iW1676, PWM Controller

The iW1676 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 protec

iW1676 Features

* while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The iW1676 removes the need for secondary feedback circuit while achieving excellent line and load regulation. It also eliminates the need for loop compensation components while mainta
