Supertex delivers sub microsecond PWM dimming with new LED driver

New from Supertex, the HV9989 is a three channel, boost LED driver integrated circuit (IC) that can drive LEDs in LCD backlighting applications. It features the company’s patented PWM dimming control algorithm that individually regulates each channel’s output current down to sub-microsecond dimming pulses, which permits dimming at frequencies outside the audible range (>20kHz) without any shift in the “white point” or the colorcorrelated temperature. It drives strings of either RGB LEDS or multiple strings of white LEDs.
