Electronic Drivers

Boost LED Driver IC delivers sub-µs PWM dimming.

Used for LCD backlighting, 3-channel HV9989 features PWM dimming control algorithm that regulates each channel's output current down to sub-Â-µs dimming pulses. This permits dimming at frequencies outside audible range without shift in color correlated temperature. Powered by 40 V linear regulator, IC drives boost or SEPIC converters in continuous or discontinuous conduction mode. Three 1...
