Datasheet Summary
G5138P Series
Digital Green-Mode Quasi-Resonant Primary-Side PWM Power Switch
1.0 General Description
The G5138P 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 to provide high efficiency along with a number of key built-in protection Features while minimizing the external ponent count, simplifying EMI design and lowering the total bill of material cost. The -K version can operate at peak power mode with momentary peak power higher than the maximum continuous output power without design cost and size increase.The G5138P removes the need for...
