Three-Channel LED Driver Includes Fault Control

Dec. 22, 2010
The HV9986 three-channel, switchmode LED driver integrates three dimmer switch FET drivers that enable high PWM dimming ratios and independent fault management.

The HV9986 three-channel, switchmode LED driver integrates three dimmer switch FET drivers that enable high PWM dimming ratios and independent fault management.  Via closed-loop control of output current, the device drives multiple strings of LEDs for edge lighting or backlighting. Switching frequencies of each channel are controllable with an external clock or the IC’s internal oscillator. Available in a 40-lead QFN package, price is $2.15 each/1,000.
