HV9967B

Integrated LED Driver

with Average-Mode Current Control

Features

► 3% accurate LED current

General Description

The HV9967B is an average-mode current control LED driver IC

operating in a constant off-time mode.

► Integrated 60V, 0.8Ω MOSFET

► Low sensitivity to external component variation

► Single resistor LED current setting

► Fixed off-time control

The IC features an integrated 60V, 0.8Ω MOSFET that can be

used as a stand-alone buck converter switch, or connected as a

source driver for driving an external high-voltage depletion-mode

MOSFET. The HV9967B is powered through its switching output

when the integrated switch is off. Hence, the same external

MOSFET can be used as a high-voltage linear regulator for

powering the IC.

► PWM dimming input

► Output short circuit protection with skip mode

► Over-temperature protection

► Available in compact 8-Lead MSOP and 8-Lead

DFN packages

The LED current is programmed with one external resistor. The

average-mode current control method does not produce a peak-

to-average error, and therefore greatly improves current accuracy

and line and load regulation of the LED current without any need

for loop compensation or direct sensing of the LED current at a

high-voltage potential. The auto-zero circuit cancels the effects of

the input offset voltage and of the propagation delay of the current

sense comparator.

Applications

► DC/DC or AC/DC LED drivers

► RGB backlighting drivers for ﬂat panel displays

► General purpose constant current source

► Signage and decorative LED lighting

► Chargers
