LNK564DN-TL

LinkSwitch-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 mW. The internal oscillator frequency is jittered to signifi cantly reduce both quasi-peak and average EMI, minimizing fi lter cost.

• Adapter: 3W
• 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 effi ciency
• 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 fi lter confi 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
