HV9910

Universal High Brightness LED Driver

Description

Features

The HV9910 is a PWM high-efficiency LED driver

control IC. It allows efficient operation of High

Brightness (HB) LEDs from voltage sources

ranging from 8VDC up to 450VDC. The HV9910

controls an external MOSFET at fixed switching

frequency up to 300kHz. The frequency can be

programmed using a single resistor. The LED string

is driven at constant current rather than constant

voltage, thus providing constant light output and

enhanced reliability. The output current can be

programmed between a few milliamps and up to

more than 1.0A.

ꢀ

>90% Efficiency

8V to 450V input range

Constant-current LED driver

Applications from a few mA to more than 1A

Output

ꢀ

LED string from one to hundreds of diodes

PWM Low-Frequency Dimming via Enable pin

Input Voltage Surge ratings up to 450V

HV9910 uses a rugged high voltage junction

isolated process that can withstand an input voltage

surge of up to 450V. Output current to an LED

string can be programmed to any value between

zero and its maximum value by applying an

external control voltage at the linear dimming

control input of the HV9910. The HV9910 provides

a 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.

Applications
