PMP4472
AC 輸入、5V/3.3V2A 串級式電源參考設計
PMP4472
概覽
The PMP4472 is a power reference design with a high AC input, 5Vout, followed by a DC isolated
output of 3.3V at 2A. It implements a high efficiency controller UCC28740 to provide 5V bus voltage and a step-Down Converter TPS54228.The design achieves good line and load regulation as well as good dynamic response and low output ripple voltage.
特點
- Isolated Flyback and Buck converter
- 2 outputs include 5V Bus voltage
- Good line and load regulation
- Good dynamic response
- Low output ripple voltage
