Introduction

AI Translation

The HV9925 is a pulse-width modulated high-efficiency LED driver control IC with PWM dimming capabilities. It allows efficient operation of high-brightness LED strings from voltage sources ranging up to 400 VDC. The HV9925 includes an internal high-voltage switching MOSFET controlled with a fixed off-time of approximately 10.5 μs. The LED string is driven at constant current, thus providing constant light output and enhanced reliability. Selecting a current sense resistor value can externally program the output LED current of the HV9925. The peak current control scheme provides good regulation of the output current throughout the universal AC line voltage range of 85 VAC to 264 VAC or DC input voltage of 20V to 400V. The HV9925 is designed with a built-in thermal shutdown to prevent excessive power dissipation in the IC.
