Description

This demonstration board implements a 18 W

non-isolated soft-switched 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.

High power factor is achieved by reshaping the

peak current nearby the zero crossing of input AC

line.
