HV9982

Three-Channel, Closed-Loop, Switch Mode LED Driver IC

General Description

Features

► Switch mode controller for single-switch converters

► Closed loop control of output current

♦ Buck

The HV9982 is a three-channel, closed loop, peak current

mode PWM controller for driving a constant output current.

It can be used for driving either RGB LEDs or multiple

channels of white LEDs.

♦ Boost

♦ SEPIC

The HV9982 includes a 40V linear regulator which provides

an 8.0V supply to power the IC. The switching frequencies

of the three converters are controlled by an external clock

signal. The channels operate at a switching frequency of

1/12^thof the external clock frequency to minimize the input

current ripple. Each converter is driven by a peak current

mode controller with output current feedback.

► High PWM dimming ratio

► Internal 40V linear regulator

► Constant frequency operation

► Programmable slope compensation

► Linear and PWM dimming

► +0.2A/-0.4A gate drives for the switching FETs

► Output short circuit protection

► Output over voltage protection

► Hiccup mode protection

The three output currents can be individually dimmed using

either linear or PWM dimming. The IC also includes three

disconnect FET drivers which enable high PWM dimming

ratios and also help to disconnect the input in case of an

output short circuit condition. HV9982 includes a hiccup

mode protection for both open LED and short circuit

condition with automatic recovery when the fault clears.

► Analog control of PWM dimming

Applications

► RGB backlight applications

► Multiple string white LED driver applications
