RT8101 Datasheet | Richtek

Description The RT8101/A are DC/DC synchronous buck PWM controllers with embedded driver support up to 12V+12V boot-strapped voltage for high efficiency power driving. The parts are with full functions of voltage regulation, power monitoring and protection into a single small footprint packages SOP-8 and SOP-8 (Exposed Pad). .. The RT8101/A apply a high-gain voltage mode PWM control for simple application design. An internal 0.8V reference allows the output voltage to be precisely regulated to low voltage requirement. The parts are proposed with two type including RT8101 and RT8101A with fixed operating frequency of 300k Hz and 600k Hz respectively. Based on the features that RT8101/A offered, the parts provide an optimum solution between efficiency, total B.O.M. count, and cost.
