RT8130C

12V Green Voltage Mode High Efficiency Synchronous

Buck PWM Controller

General Description

Features

^Green Voltage Mode (GVM^TM) Control

The RT8130C is a high efficiency single phase

^High Light Load Efficiency

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

voltage. The IC features Green Voltage Mode (GVM^TM

)

^Single 5V to 12V Driver Voltage

^Integrated High Driving Capability N-MOSFET Gate

Drivers

control, which is specifically designed to improve converter

efficiency at light load condition. At light load condition,

the IC automatically operates in the diode emulation mode

with constant on-time PFM to reduce switching frequency

so as to improve conversion efficiency.As the load current

increases, the RT8130C leaves theDiode Emulation Mode

(DEM) and operates in the continuous conduction mode

with fixed frequency PWM.

^300kHz Fixed Frequency Internal Oscillator

^88% Maximum PWM Duty Cycle

^Power Good Indicator

^Enable/Disable Control

^Adaptive Zero-Current Detection

^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

The RT8130C 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 RT8130C 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

RT8130C is available in the WDFN-10L 3x3 package.
