RT8525DGQW
DC/DC Controller, Boost, Step Up, 4.5 V to 25 V Supply, 90 % Duty Cycle, 200 kHz, WDFN-12
Product Information
Product Overview
The RT8525DGQW from Richtek is a current mode boost controller in 12 lead WDFN package. This 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. It is an optimized design for wide output voltage range applications. It is used in LCD TV, monitor display backlight, LED driver application, high current high output voltage DC/DC converters and high input voltage DC/DC converters.
