Powerint PKS607YN 54W音频放大器电源RDR-203设计方案
PeakSwitch is designed to address applications with high peak-to-continuous power ratio demands. The very high switching frequency during peak power loads and excellent load transient response reduce system cost as well as component count and size. PeakSwitch incorporates a 700 V power MOSFET, oscillator, high voltage switched current source for startup, current limit, and thermal shutdown onto a monolithic device. In addition, these devices incorporate auto-restart, line under-voltage sense and frequency jittering. An innovative design minimizes audio frequency components in the simple ON/OFF control scheme to practically eliminate audible noise with standard varnished transformer construction.
