RT8130B

12V High Efficiency Synchronous Buck PWM Controller

General Description

Features

^High Light Load Efficiency

The RT8130B is a high efficiency single phase

synchronous Buck DC/DC controller with 5V/12V supply

voltage.

^Single 5V to 12V Driver Voltage

^Integrated High Driving Capability N-MOSFET Gate

Drivers

The RT8130B has embedded MOSFET gate driver with

high driving capability, supporting driving voltage up to 12V

for high output current application. This device uses

lossless low-side MOSFET R_DS(ON)current sense

technique for over-current protection with adjustable

threshold set by the LGATE pin (LGOCS). Other features

include power good indication, enable/disable control and

internal soft-start. The RT8130B also provides fault

protection functions to protect the power stage output.

With above functions, the IC provides customers a cost-

effective solution for high efficiency power conversion. The

RT8130B is available in the WDFN-10L 3x3 package.

^300kHz Fixed Frequency Internal Oscillator

^88% Maximum PWM Duty Cycle

^Power Good Indicator

^Enable/Disable Control

^Internal Soft-Start

^Lossless Low-Side MOSFET R_DS(ON)Current Sensing

for Over-Current Fault Monitoring

^LGATE Over-Current Setting (LGOCS)

 OCP, UVP, OVP, OTP, UVLO
