PMP21513
适用于音频应用的 25/50W 反激式参考设计
PMP21513
概述
The quasi-resonant flyback design is a dual output converter with a 24 Volt output and a 6 Volt output. The voltages that are supplied are important for supplying power in audio applications. The design is very low noise for sensitive audio signals with less than 2.5 % voltage ripple on the 24 V output.
特性
- 90 VAC - 264 VAC input to 24 V/2.2 A isolated output
- Secondary output of 6 V/200 mA put through an LDO to output 3.3 V/200 mA to reduce noise
- Up to 88.8% Efficiency at full load without the need for a synchronous rectifier
- Stacked windings to improve regulation of 6 V line
