An enable input facilitates PWM dimming of the entire LED load. The output current of the IC can be programmed between 20 and 50mA by a single resistor. The HV9925 also includes an internal 500V switching MOSFET and built in thermal shutdown to prevent excessive power dissipation. The IC accepts inputs of 85-264V AC and 20-400V DC.
"With an adjustable output current and PWM dimming capability, the HV9925 is an efficient and flexible solution for numerous LED driving applications," states Ahmed Masood, Vice President of Marketing at Supertex. "The development of this IC further strengthens Supertex's commitment to and leadership position in the LED driver market, and broadens our family of LED drivers."
The HV9925 is available in an eight pin SOIC package (HV9925SG-G). Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$0.78 each for the HV9925SG-G in 1K quantities.
