RT8525D
RT8525D is Current Mode Boost Controller manufactured by Richtek.
Description
The RT8525D 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 RT8525D input operating range is from 4.5V to 25V.
The RT8525D is an optimized design for wide output voltage range applications. The output voltage of the RT8525D can be adjusted by the FB pin.
