Design guide for LED Lighting Controller XC9401(1/9)

1. General Description

The XC9401 series are offline controller ICs for LED lighting. By optimizing external components, operation from 85VAC to 270VAC is possible, as well as operation by DC input, and a wide variety of specifications can be realized by selecting components appropriate for the circuit configuration. These application notes describe the operation of both non-isolated and isolated LED lighting, and how to select components.
