The RT8525 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 RT8525 input operating range is from 4.5V to 29V.
The RT8525 is an optimized design for wide output voltage range applications. The output voltage of the RT8525 can be adjusted by the FB pin. The PWMI pin can be used as a digital input, allowing WLED brightness control with a logic-level PWM signal.
