  HV9925SG-G - LED-Treiber, 7 Arrays, SO-8

  The HV9925 is a pulse width modulated (PWM) 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 V DC. The HV9925 includes an internal high-voltage switching MOSFET controlled with a fixed off-time (TOFF) of approximately 10.5 µs. The LED string is driven at constant current, thus providing constant light output and enhanced reliability. Selecting a value of a current sense resistor 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 ... 264 V AC or DC input voltage of 20 ... 400 V. The HV9925 is designed with a built in thermal shutdown to prevent excessive power dissipation in the IC.• Programmable output current to 50 mA• PWM dimming / enable• Universal 85 - 264 V AC operation• Fixed off-time buck converter• Internal 475 V power MOSFET• Over-temperature protection with hysteresis Technical Data: • Topology: Buck• Input Voltage: 20 ... 400 V• Output Current: 20 ... 50 mA• Power: 800 mW
