HV9910  
Universal High Brightness LED Driver  
Description  
Features  
The HV9910 is a PWM high-efficiency LED driver  
control IC. It allows efficient operation of High  
Brightness (HB) LEDs from voltage sources  
ranging from 8VDC up to 450VDC. The HV9910  
controls an external MOSFET at fixed switching  
frequency up to 300kHz. The frequency can be  
programmed using a single resistor. The LED string  
is driven at constant current rather than constant  
voltage, thus providing constant light output and  
enhanced reliability. The output current can be  
programmed between a few milliamps and up to  
more than 1.0A.  
>90% Efficiency  
8V to 450V input range  
Constant-current LED driver  
Applications from a few mA to more than 1A  
Output  
LED string from one to hundreds of diodes  
PWM Low-Frequency Dimming via Enable pin  
Input Voltage Surge ratings up to 450V  
HV9910 uses a rugged high voltage junction  
isolated process that can withstand an input voltage  
surge of up to 450V. Output current to an LED  
string can be programmed to any value between  
zero and its maximum value by applying an  
external control voltage at the linear dimming  
control input of the HV9910. The HV9910 provides  
a low-frequency PWM dimming input that can  
accept an external control signal with a duty ratio of  
0-100% and a frequency of up to a few kilohertz.  
Applications  
DC/DC or AC/DC LED Driver applications  
RGB Backlighting LED Driver  
Back Lighting of Flat Panel Displays  
General purpose constant current source  
Signage and Decorative LED Lighting  
Automotive  
Chargers  
Typical Application  
C110504
