G5177 Digital Green-Mode PWM Controller

The G5177 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.

G5177 Features

* while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The device together with an external active device (depletion mode NFET or NPN BJT) provides a fast start-up without compromising no-load power loss. Global Semiconductor’s innovative
