G5176

G5176 Low-Power Off-Line Digital Green-Mode PWM Controller DIGITAL PWM IC 1.0 General Description The G5176 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 protection features while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. Global-Semi’s innovative proprietary technology ensures that with low system cost, power supplies built with the G5176 can achieve both highest average efficiency, less than 30mW no-load power consumption and fast dynamic load response in a compact form factor. The G5176 removes the need for secondary feedback circuitry while achieving excellent line and load regulation. It also eliminates the need for loop compensation components while maintaining stability over al...
