适用于噪声敏感型负载的反向 SEPIC 参考设计
PMP30487
概述
This reference design is an inverting SEPIC (Cuk) Converter powering 50-W continuous and up to 70-W peak. The used Cuk topology provides continuous currents at input and output, which allows the lowest conducted emissions in both directions. Compared to an inverting flyback radiated emissions are low as well due to no RF ringing at the switch node.
特性
- Best EMI behavior compared to inverting buck boost or inverting flyback
- A high full load efficiency of 94%
- Transient response is better than 1% for 50% load range
- Output voltage is regulated very tight over the whole input voltage range (28 V to 42 V)
- Load regulation is tight over the whole output current range
- UVLO functionality is integrated
