Description

The STEVAL-ILL027V2 implements a non-

isolated, soft-switched, single-stage, high power

factor offline LED driver.

The buck-boost converter is chosen for this

application due to its simplicity and low cost.

The converter operates with constant peak

current for constant power control and in transition

mode (boundary mode between CCM and DCM),

to achieve soft switching, using the L6562A

controller.

This single-stage buck-boost converter provides a

cost-effective solution for offline non-isolated LED

applications and it also has open load and short-

circuit protection.
