Product Summary

The RT8101AGSP is a DC/DC synchronous buck PWM controller 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 single small footprint packages SOP-8 and SOP-8 (Exposed Pad). The RT8101AGSP applies 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 applications of the RT8101AGSP include Graphic Card, Motherboard, Desktop Servers, IA Equipments, Telecomm Equipments, and High Power DC-DC Regulators.
