G5138P 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 component count, simplifying EMI design and lowering the total bill of material cost.
The G5138P 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 a...
