Switching regulator with extended power range TinySwitch-III

Simple ON/OFF control, no loop compensation needed Selectable current limit through BP/M capacitor value Higher current limit extends peak power or, in open frame applications, maximum continuous power Tight I2f parameter tolerance reduces system cost; minimizes maximum overload power, reducing cost of transformer, primary clamp & secondary components On-time extensionextends low line regulation range/hold-up time to reduce input bulk capacitance Frequency jittering reduces EMI filter costs Applications: Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers etc. PC Standby and other auxiliary supplies DVD/PVR and other low power set-top decoders Supplies for appliances, industrial systems, metering etc
