Preliminary

VP2123

3A/25V/340kHz Synchronous Buck Converter

General Description

Features

The VP2123 is an efficiency and low-cost buck

converter with integrated low R_DS(ON)high-side

90mΩ and low-side 80mΩ MOSFET switches. It is

capable of delivering 3A output current over a wide

range of supplying voltage from 5V to 25V. With a

simple voltage divider, the output voltage is easily

adjustable from 0.922V to 15V.

5V to 25V Input Voltage Range

Adjustable Output from 0.922V to 15V

Continuous 3A Output Current

Integrated 90mΩ/80mΩ MOSFET Switches

0.922V Voltage Reference with ±2% Accuracy

94% Conversion Efficiency at 5V/2A Output

Programmable Soft-Start Function

Low 1.1mA Quiescent Current

Fixed 340kHz Switching Frequency

Adapted Current Mode PWM Operation

Under Voltage Lock-Out Protection

Over Voltage and Current Limit

Other features such as programmable soft-start,

integrated Boot-Diode, total fault-free protection

and 94% conversion efficiency at 5V/2A output

make VP2123 ideally to be used in portable con-

sumer electronics.

Over Temperature Protection

RoHS 2.0 compliant SO-8P Green Package

with Exposed Pad

The VP2123 is available in popular SO-8P green

package with exposed pad.

Applications

Set-Top Box

Networking Device

LCD Monitor/ LCD TV

Typical Application
