RT9288A
Description
The RT9288A is a wide input operating voltage range stepup controller. High voltage output and large output current are feasible by using an external N-MOSFET. The RT9288A input operating range is from 3V to 13.5V. Besides, it could support up to 60V output at 12V input.
The RT9288A is an optimized design for WLED driver applications. Adjusting the output current of the RT9288A changes the brightness of the WLEDs. Chip Enable pin can be used as a digital input allowing WLED brightness control with a logic-level PWM signal.
