DI-172, LNK306PN, High Efficiency Constant Current Buck Converter for LED Lighting
Reference design by: Power Integrations
DI-172, Reference Design for Power supply uses LNK306PN, LinkSwitch-TN device in a low side buck converter configuration to deliver a constant current of 130mA at a voltage of 70VDC. The supply provides an ideal solution for driving LEDs that should be driven with a constant current rather than a constant voltage source
