RT8124A

5V to 12V Single Synchronous Buck PWM Controller

General Description

Features

^zSingle IC Supply Voltage (5V to 12V)

The RT8124Ais a single-phase synchronous buck PWM

DC-DC controllers designed to drive two N-MOSFETs. It

provides a highly accurate, programmable output voltage

precisely regulated to low voltage requirement with an

internal 0.6V reference.

^zDrive Two N-MOSFETs

^zFixed Operating Frequency at 300kHz

^zVoltage Mode PWM Control with External

Feedback Loop Compensation

^zOver Current Protection by Sensing MOSFET R_DS(ON)

^zHardware Pin for On/Off Control

^zFull 0 to 90% Duty Cycle

The RT8124Auses a single feedback loop voltage mode

PWM control for fast transient response. The high driving

capability makes it suitable for large output current

applications. An oscillator with fixed frequency 300kHz

reduces the component size of the external inductor and

capacitor for saving PCB board area and cost.

^zFast Transient Response

^zRoHS Compliant and Halogen Free

Applications

z Mother Boards andDesktop Servers

The RT8124A integrates complete protection functions

such as OCP, OVP and OTP UVP into a WDFN-10L 3x3

package.

z Graphic Cards

z Switching Power Supply

z GenericDC/DC Power Regulator
