Power Integrations LNK564PN High Side 1, Off Liner Power Switch IC 8-Pin, DIP-B

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
