HV9980

3-Channel LED Array Driver IC

illumination. The output currents are programmed by

controlling peak source current in each of the three internal

200V, 25Ω switching MOSFETs.

Features

► Integrated 200V, 25Ω (typ.) MOSFETs

► Programmable output current to 80mA per channel

► TTL compatible PWM dimming inputs

► 3-Phase synchronous operation

► Leading edge blanking

Thepeak currentisdetected bymonitoring voltage atexternal

sense resistors connected to RSENSE1-3. The switching

MOSFET is turned off when the corresponding current sense

signal exceeds the reference voltage applied at REF1-3 (in

the case of normal output signal polarity). Beginning of the

next switching cycle is determined by the external clock

signal received at the CLK input. All three channels operate

at a switching frequency of 1/6 of the external clock frequency

and positioned 120º out-of-phase for the purpose of input and

output ripple current reduction. Each channel is protected

from an output short circuit condition. When an over-current

condition is detected in the output switch (RSENSE1-3),

the corresponding channel shuts down for 200us. HV9980

recovers automatically, when the short circuit condition is

removed. Each current sense input (CS1-CS3) is equipped

with a leading edge blanking delay to prevent false triggering

of the current sense comparators due to circuit parasitics.

► Short circuit protection with skip mode

► Over-temperature protection

Applications

► LCD panel backlighting

► DLP RPTV or projector LED engine driver

► RGB decorative lighting

► General LED lighting

General Description

The HV9980 is a fully integrated 3-channel peak-current

PWM controller for driving buck converters in constant output

current mode. It is optimized for use with a large array of

20~80mA LED strings, where multiple HV9980 ICs are used

sharing a common clock and a common reference voltage.

Over-temperature protection is included to prevent

destructive failures due to over-heating. Programmable

slope compensation is available at each CS input.AGND and

PGND1-3 must be tied together on the printed circuit board.

VDD1-3 must be also connected together on the PCB.

Both the clock and the voltage reference are external to the

HV9980 for improved output current accuracy and uniform
