Low Component Count, Isolated 350 mA, 4.2 W LED Driver

Focus:

A design based on the LNK605DG LinkSwitch-II chip implements a universal-input, 12-V 350-mA output CV/CC power supply for driving LEDs. This isolated flyback design achieves a low component count. The reference design bill-of-materials lists 32 components. This design meets all existing and proposed energy efficiency standards including including EPA, CEC, European Commission, and China (CECP).

What you’ll learn:

• How to build a universal-input, 12-V 350-mA output, isolated CV/CC power supply for driving high-power LEDs
