The TPS92633 is a three-channel linear LED driver with a wide input voltage range up to 40V. It features 3-channel high-precision current regulation with support for external NTC for current derating and off-board brightness binning resistors. The device includes individual PWM pins for brightness control and a thermal sharing mechanism to distribute power dissipation. Integrated protection includes LED short-to-ground, LED open-circuit, and single LED shorted detection with auto-recovery and a configurable fault bus.
