PMP30555
用于辅助电源的 3.5W 隔离式推挽参考设计
PMP30555
概述
This reference design is an isolated open-loop push-pull with “cascode” FETs that finds its typical application in isolated gate drive supply. The cascode connection extends the input voltage range of SN6505B from 5 V to 24 V, and two outputs supply 15 V at 120 mA and 5 V at 350 mA. Its 2-mm transformer makes the solution ultra-thin.
特性
- Low-noise, high-voltage isolation
- No loop compensation (open loop)
- Suitable for multi-output applications
- No inductor on secondary side
