The HV9989K6-G-M935 is a three-channel boost LED driver designed for constant-current applications, suitable for driving RGB or multiple white LEDs. It operates in both Continuous-Conduction Mode (CCM) and Discontinuous-Conduction Mode (DCM), featuring a proprietary PWM-dimming control algorithm that allows for sub-microsecond dimming pulses and a dimming frequency exceeding 20 kHz. Each channel has independent PWM dimming and reference voltage inputs, enabling precise control over LED brightness. The device includes a built-in 40V linear regulator and supports external clock synchronization, allowing the three channels to operate at a frequency of 1/12th of the external clock frequency while being 120¬8 out-of-phase to minimize input current ripple. Protection features include independent short circuit protection with hiccup mode and latching output open-circuit protection for each channel. The HV9989K6-G-M935 is suitable for applications such as LCD panel back-lighting and operates within a temperature range of -40¬8C to 85¬8C.
