The RT8101/A are DC/DC synchronous buck PWMcontrollers with embedded driver support up to 12V+12Vboot-strapped voltage for high efficiency power driving. Theparts are with full functions of voltage regulation, powermonitoring and protection into a single small footprintpackages SOP-8 and SOP-8 (Exposed Pad).The RT8101/A apply a high-gain voltage mode PWM controlfor simple application design. An internal 0.8V referenceallows the output voltage to be precisely regulated to lowvoltage requirement. The parts are proposed with two typeincluding RT8101 and RT8101A with fixed operatingfrequency of 300kHz and 600kHz respectively. Based onthe features that RT8101/A offered, the parts provide anoptimum solution between efficiency, total B.O.M. count,and cost.
