具有负载自适应损耗及256倍亚毫瓦级负载瞬态响应

The authors propose a pulse-frequency modulation based buck converter that uses synchronous control. The controller clock continuously tracks twice the switching frequency through internal control that employs a primary clock. The system responds to 256x load rise transients within four switching periods using synchronous control to have fine output voltage attributes with a 27 nF-capacitor at out...
