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
