The MXHV9910 from IXYS (http://) is a low-cost, high-brightness (HB) LED driver manufactured using Clares high-voltage BCDMOS on SOI process. The driver has internal circuitry that allows it to operate From a universal AC line or from 8Vdc to 450Vdc.
This highly versatile input operating voltage enables this device to be used in a broad range of HB LED applications.
MXHV9910 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 a Low-frequency digital PWM signal to the PWMD pin.
Included a 8V to 450V input voltage range, it has >90% efficiency and drivers multiple LEDs in series/parallel combinations. Other attractions include regulated LED drive current, linear or PWM brightness control and resistor-programmable oscillator frequency.
Package is in SOIC-8 and SOIC-8 EP (Exposed Thermal Pad).
