Key Features
while minimizing the external component count, simplifying EMI design and lowering the total bill of material cost. The G5175 features a distinctive soft-start scheme, which allows for fast and yet smooth start-up with both small and large capacitive loads. Global Semiconductor’s innovative proprietary technology ensures that power supplies built with the G5175 can achieve both highest average efficiency and fast yet smooth start-up with a wide range of capacitive loads, and are ideal for networ.
