LNK563P
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.
- 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 efficiency
- 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 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 compensation needed
