APPLICATION NOTE
DESIGN TIPS FOR L6561 POWER FACTOR CORRECTOR
IN WIDE RANGE
by Cliff Ortmeyer & Claudio Adragna




This application note will describe some basic steps to optimize the design of the L6561 PFC for wide
range voltage input (105V- 300V) while also having a broad output power range (65W - 105W). Initial
design steps are covered in application note AN966. This is to serve as a supplement to that applica-
tion
