Driver Also Protects LEDs

The HV9860 LED driver promises to extend LED life in applications such as RGB or white LED backlighting, LCD TVs and monitors, and LED lamps. The device uses a peak-current mode control scheme and includes an internal transconductance amplifier to control output current over all line and load conditions. It also includes LED wiring fault detection to protect LED strings from high current in short-circuit conditions. The HV9860 is available in a 16-lead SOIC package (HV9860NG-G). Pricing is $0.95 each/1,000. SUPERTEX INC., Sunnyvale, CA. (800) 222-9883.
