LNK564GN-TL Datasheet

AC/DC Switching Converters


LNK564GN-TL switcher ICs cost effectively replace all unregulated isolated linear transformer based (50/60 Hz) power supplies up to 3 W output power. For worldwide operation, a single universal input design replaces multiple linear transformer based designs. The self-biased circuit achieves an extremely low no-load consumption of under 150 mW. The internal oscillator frequency is jittered to signi cantly reduce both quasi-peak and average EMI, minimizing lter cost. LNK564GN-TL Features • Lowest component count switcher • Very tight parameter tolerances using proprietary IC trimming technology and transformer construction techniques enable Clampless™designs – decreases component count/system cost and increases efciency• Meets industry standard requirements for thermal overload protection – eliminates the thermal fuse used with linear transformers or additional components in RCC designs • Frequency jittering greatly reduces EMI – enables low cost input lter con guration• Meets HV creepage requirements between DRAIN and all other pins, both on the PCB and at the package• Proprietary E-Shield™ transformer eliminates Y-capacitor LNK564GN-TL Applications • Chargers for cell/cordless phones, PDAs, power tools, MP3/portable audio devices, shavers etc.• Standby and auxiliary supplies
