具有扩展输入电压范围的 30W SEPIC 参考设计
PMP30465
概述
This reference design is a wide input voltage range SEPIC converter delivering up to 30-W continuous output power using a cost-effective, discrete startup circuitry that allows it to be supplied up to a 80-V input. Another discrete UVLO circuitry prevents from large input currents at low input voltage, so the power supply is able to handle an input range of 1:8. The internal driver of the controller is boosted by a small external push- pull stage using bipolar transistors. This allows it to be used with a coupled inductor from stock results in less amount and stress for the flying capacitors. Furthermore, there is no need for additional damping RC network.
特性
- Increased driver sink/source capability by an external push-pull stage
- Low impedance capacitance ladder at output to reduce ripple and noise
- Measures were taken to reduce switching noise at FET and rectifier
- Cost-effective solution by adding several discrete features to TPS40210
