PMP20814
3.75W 单路输出工业 PoE 隔离式 Flybuck 参考设计
PMP20814
概述
PMP20814 is an isolated Flybuck converter utilizing the LM5018 for industrial applications. This design has a minimum operating input voltage of 43V and a maximum input voltage of 53V. The design has a primary output of 7.35V and a secondary output capable of sourcing 0.25A continuous current at 15Vout. Switching frequency is set to 250kHz. A custom transformer is used. PMP10543’s PCB was used to build the design.
特性
- Primary side regulation without opto, good regulation, within +/-5%
- No loop compensation required/fast transient response
- Low BOM count and cost, compact solution size
- No RC snubber at primary winding
