LNK564D Datasheet | Power Integrations

Features - Lowest ponent count switcher - Very tight parameter tolerances using proprietary IC trimming technology and transformer construction techniques enable Clampless™designs - decreases ponent count/system cost and increases efficiency - Meets industry standard requirements for thermal overload protection - eliminates the thermal fuse used with linear transformers or additional ponents in RCC designs - Frequency jittering greatly reduces EMI - enables low cost input filter configuration - 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 Superior Performance over Linear and RCC - Hysteretic thermal shutdown protection - automatic recovery improves field reliability - Universal input range allows worldwide operation - Auto-restart reduces delivered power by >85% during short circuit and open loop fault conditions - Simple ON/OFF control, no loop pensation needed - High bandwidth provides fast turn on with no overshoot and excellent transient load response Eco Smart®- Energy Efficiency Technology - Easily meets all global energy efficiency regulations with no added ponents - No-load consumption <150 m W at 265 VAC input - ON/OFF control provides constant efficiency to very light loads - ideal for mandatory CEC regulations Applications - Chargers for cell/cordless phones, PDAs, power tools, MP3/portable audio devices, shavers etc. - Standby and auxiliary supplies Description Link Switch-LP 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 m W. The internal oscillator frequency is jittered to significantly reduce both quasi-peak and average EMI, minimizing filter cost. AC IN + DC Output Link...
