Description

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

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.

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)
