Littelfuse, Inc. High-voltage AC mains powered high brightness LED Driver ICs MXHV9910

MXHV9910 is a low cost, high-brightness (HB) LED driver manufactured using our high voltage BCDMOS on SOI process. This 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 range 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. 8V to 450 V Input Voltage Range >90 % Efficiency Drives Multiple LEDs in Series and Parallel Configurations Regulated LED Drive Current Linear or PWM Brightness Control Resistor-Programmabl e Oscillator Frequency SOIC-8 and SOIC-8 EP (Exposed Thermal Pad) Packages
