MXHV9910

Off-Line, High Brightness LED Driver

Features

Description

• 8V to 450V Input Voltage Range

• >90% Efficiency

The MXHV9910 is a low-cost, high-brightness (HB)

LED driver manufactured using Clare’s high-voltage

BCDMOS on SOI process. This driver has internal

circuitry that allows it to operate from a universal AC

line or from 8V to 450V . This highly versatile

• Drives Multiple LEDs in Series/Parallel

Combinations

• Regulated LED Drive Current

• Linear or PWM Brightness Control

• Resistor-Programmable Oscillator Frequency

• RoHS Compliant

input operating voltage enables this IC to be used in a

broad range of HB LED applications.

The driver features a fixed-frequency, peak-current

control method, which provides an ideal solution for

driving multiple LEDs in series and in parallel. In

addition, LED dimming can be implemented by

applying a small DC voltage to the LD pin, or by

applying a low-frequency digital PWM signal to the

PWMD pin.

Applications

• Flat-Panel Display RGB Backlighting

• Signage and Decorative LED Lighting

• DC/DC or AC/DC LED Driver Applications

The MXHV9910 is available in a standard 8-lead SOIC

package and a thermally enhanced 8-lead SOIC

package with an Exposed Thermal Pad (EP)
