basicInfoDescription
basicInfoImageSwitcher
The RT9288A is a wide input operating voltage range step-up 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.<br />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.
