General Description

The CDB1601-120W board demonstrates the perfor-

mance of the CS1601 digital PFC controller as a stand-

alone unit. This board is 95% efficient at full load, and

has been tailored for use with a resonant second stage

to power up to two T5 fluorescent lamps for a maximum

output power of 108W. A resonant second stage driver

efficiency of 94% is assumed for this application.

CDB1601-120W 1. INTRODUCTION The CS1601 is a high-performance Variable Frequency Discontinuous Conduction Mode (VF-DCM), active Power Factor Correction (PFC) controller, optimized to deliver the lowest PFC system cost for electronic ballast applications. The CS1601 uses a digital control algorithm that is optimized for high efficiency and near unity power factor over a wide input voltage range (108-305 VAC). The CS1601 uses an adaptive digital control algorithm.
