LNK564G Overview
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.
LNK564G Key Features
- Lowest ponent count switcher
- Very tight parameter tolerances using proprietary IC
- 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
- Hysteretic thermal shutdown protection
LNK564G Applications
- Chargers for cell/cordless phones, PDAs, power tools
