HV9904DB1

Off-Line Current Source Controller

Introduction

Specification

The Supertex HV9904DB1 demo board is an LED

driver circuit using the HV9904. A power converter of

the demo board consists of an input buck-boost stage

and an output buck stage. The output voltage polarity

is negative. Due to its double down conversion

topology, the converter can operate directly off of AC

line to produce low-voltage output without use of a

transformer. The converter does not require any

electrolytic capacitors and maintains output current

with low peak-to-average ratio.

Output Power

Efficiency

80 to 135VAC, 60Hz

20V max

2W max

62% at Io=500mA, Vin=100VAC

The circuit is practical for up to 2W of output power. It

features low cost and very high reliability

Board Layout and Connections

WARNING!!!

Do not connect to scope ground or to the ground of other earth-grounded instruments. Doing so will short the AC line,

resulting in damage to the circuit and/or instruments. Either use an isolation transformer on the AC line, use a

differential probe, or use a floating, battery-powered instrument to make measurements.

WARNING!!!

No galvanic isolation. Dangerous voltages are present when connected to the AC mains.
