LinkSwitch-PL series LED driver circuit diagram

Powerint's DER322 reference design uses the LinkSwitch -PL series LNK460VG device. It is the industry's first LED driver that can replace 100W A19 incandescent lamps . It uses a single-layer PCB, has the characteristics of low cost, low component count and small size. At 230V AC , the efficiency is greater than 93%, PF greater than 0.9, 230 V AC ; THD less than 20% at 78 V LED, integrated package protection and reliability features, automatic recovery from thermal shutdown. This article introduces the circuit diagram of a 5W 15V LED driver using the LinkSwitch-PL series to replace the A19 incandescent lamp .
