The Q48SG series provide up to 400 watts of power in an industry standard, DOSA compliant With heatspreader footprint and pin out the typical efficiency is 96% at 48V input, Short pin lengths available 11.8V output and 34A load. There is a built-in digital PWM controller in the Q48SG series, which is used to complete the Vo feedback, PWM signal generation, droop current sharing, fault protection, and PWBUS communications, and so on. With the digital control, many APPLICATIONS design and application flexibility, advanced performance, and Telecom / DataCom reliability are obtained and the Q48SG series can be connected in Wireless Networks parallel directly for higher power without add external oring-fet.
