XRP6124

Non-Synchronous PFET Step-Down Controller

January 2011

Rev. 1.1.0

GENERAL DESCRIPTION

APPLICATIONS

The XRP6124 is a non synchronous step down

(buck) controller for up to 5Amps point of

loads. A wide 3V to 30V input voltage range

allows for single supply operations from

industry standard 3.3V, 5V, 12V and 24V

power rails.

• Point of Load Conversions

• Audio-Video Equipments

• Industrial and Medical Equipments

• Distributed Power Architecture

With a proprietary Constant On-Time (COT)

control scheme, the XRP6124 provides

extremely fast line and load transient response

while the operating frequency remains nearly

constant. It requires no loop compensation

hence simplifying circuit implementation and

reducing overall component count. The

XRP76124 also implements an emulated ESR

circuitry allowing usage of ceramic output

capacitors and insuring stable operations

without the use of extra external components.

FEATURES

• 5A Point-of-Load Capable

− Down to 1.2V Output Voltage Conversion

• Wide Input Voltage Range

− 3V to 18V: XRP6124

− 4.5V to 30V: XRP6124HV

• Constant On-Time Operations

− Constant Frequency Operations

− No External Compensation

Built-in soft start prevents high inrush currents

while under voltage lock-out and output short

protections insure safe operations under

abnormal operating conditions.

− Supports Ceramic Output Capacitors

• Built-in 2ms Soft Start

• Short Circuit Protection

• <1µA shutdown current

The XRP6124 is available in a RoHS compliant,

green/halogen free space-saving 5-pin SOT23

package.

• RoHS Compliant, Green/Halogen Free

5-pin SOT23 Package
