G5138P Datasheet | Global Semiconductor

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 G5138P removes the need for secondary feedback circuit while achieving excellent line and load regulation. It also eliminates the need for loop pensation ponents while maintaining stability over all operating conditions. Pulse-by-pulse waveform analysis allows for a loop response that is much faster than traditional solutions, resulting in improved dynamic load response for both one-time and repetitive load transients. The built-in power limit function enables optimized transformer design...
