Demonstration Board

Features

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), ac-

tive Power Factor Correction (PFC) controller, optimized to deliver the lowest PFC system cost for elec-

tronic 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. Both the ON time and the switching frequency are

varied on a cycle-by-cycle basis over the entire AC line to achieve close to unity power factor. The varia-

tion in switching frequency also provides a spread frequency spectrum, thus minimizing the conducted

EMI filtering requirements.

The feedback loop is closed through an integrated digital control system within the IC. Protection features

such as overvoltage, overcurrent, overpower, open circuit, overtemperature, and brownout help protect

the device during abnormal transient conditions. Details of these features are provided in the CS1601 data

sheet.

The CDB1601-120W board demonstrates the performance of the CS1601 over a wide input voltage range

of 108 to 305 VAC, typically seen in universal input ballast applications. This board has been designed

for a 460 V, 115 W full load output application.

Extreme caution needs to be exercised while handling this board. This board is to be powered up by

trained professionals only.

Prior to applying AC power to the CDB1601-120W board, the CS1601 needs to be biased using an exter-

nal 13 VDC power supply, applied across pins 1 and 3 of terminal block J5. Terminal block J6 is used to

connect the AC line. The load is connected to J7. As a safety measure, jumper J1 is provided as a means

to apply a small resistive load (200 kΩ minium) to rapidly discharge the output capacitors. Other jumpers

and test points are provided to evaluate the behavior of the IC and the various sections of the design.

ONLY QUALIFIED PERSONNEL SHOULD HANDLE THE CDB1601-120W.

WARNING:

Heatsinking is required for Q4.

The end product should use tar pitch or an equivalent compound for this purpose.

For lab evaluation purposes, a fan is recommended to provide adequate cooling.
