Power Integrations LNK562GN, Off Line Power Switch IC 8-Pin, SMDB

The LinkSwitch-LP family provides very low power AC-DC power conversion.

700 V Internal MOSFET Rating
Self-Powered
ON/OFF Control
Hysteretic Overtemperature Protection
Power Limiting
Frequency Jitter Reduces EMI
EcoSmart® Low Standby/No-load Power Consumption

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 significantly reduce both quasi-peak and average EMI.

Lowest component count switcher
Hysteretic thermal shutdown protection
Frequency jittering greatly reduces EMI
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
High bandwidth provides fast turn on with no overshoot and excellent transient load response
