Preliminary

RT8101/A

12V Synchronous Buck PWM DC-DC

General Description

Features

^zSingle 12V Bias Supply

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).

^zDrives All Low Cost N-MOSFETs

^zHigh-Gain Voltage Model PWM Control

^z300kHz/600kHz Fixed Frequency Oscillator

^zFast Transient Response :

`High-Speed GM Amplifier

`Full 0 to 100% Duty Ratio

The RT8101/Aapply 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 300kHz and 600kHz respectively. Based on

the features that RT8101/A offered, the parts provide an

optimum solution between efficiency, total B.O.M. count,

and cost.

`External Compensation in the Control Loop

^zInternal Soft-Start

^zAdaptive Non-Overlapping Gate Driver

^zOver-Current Fault Monitor on MOSFET, No

Current Sense Resistor Required

^zRoHS Compliant and 100% Lead (Pb)-Free

Applications

z Graphic Card

z Motherboard, Desktop Servers

z IA Equipments
