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
line or from 8V
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)
