HV9860

Single Channel Boost LED Driver

with LED Wiring Fault Detection

Features

General Description

► Switch mode controller for boost and ﬂyback

The HV9860 is a current mode control LED driver IC designed

to control a boost or ﬂyback LED driver in constant frequency

mode. The controller uses a peak current-mode control scheme

and includes an internal transconductance ampliﬁer to accurately

control the output current over all line and load conditions. The IC

also provides a disconnect switch gate drive output, which can be

used to achieve good PWM rise and fall times for the LED current

using an external disconnect FET.

converters

► Discontinuous conduction mode of operation

► High output current accuracy

► Internal ±2% voltage reference (0^OC < T_A< 125^OC)

► Internally ﬁxed 100kHz switching frequency

► Hiccup mode protection for both short circuit and

open circuit conditions

► LED wiring fault detection to detect short

The HV9860 also has a DUTY pin which can be used to set the

maximum duty cycle to either 90%(typ) or 75%(typ). The 75%

duty cycle limit can be used for ﬂyback applications.

cathode to ground condition

Applications

► DC/DC LED driver applications

► RGB or white LED backlight applications

► Flat panel display backlighting

It also provides a TTL compatible, low-frequency PWM dimming

input that can accept an external control signal with a duty ratio

of 0-100% and a frequency of up to a few kilohertz. It includes a

wiring fault detection function that sends a ﬂag to the boost input

power supply in case of an LED to wiring fault.
