3A 1.4MHz 5.5V SYNCHRONOUS BUCK CONVERTER

DESCRIPTION

FEATURES

The A7130 is a synchronous, 1.4MHz, fix frequency

PWM Buck converter. It is ideal for powering portable

equipment that powered by a single cell Lithium-ion

battery, or USB port. The A7130 can provide up to 3A

of load current with output voltage as low as 0.8V. It

can operate at 100% duty cycle for low dropout

application. With its peak current mode control and

outside compensation, the A7130 is stable with

ceramic capacitors and small inductors.



Adjustable Output Voltage, 0.8 - V_IN

High efficiency, up to 96%

Output voltage accuracy 2%

0.1ohm R_DSONof internal MOSFET

3A maximum output current

Up to 1.5MHz fix switching frequency

5.5V maximum operation voltage

Short circuit protection

Thermal shutdown protection

10mV Load regulation at 3A load

Compatible with ceramic output capacitor

Excellent load transient performance

In-rush current suppression

A7130 comprises a cycle-by-cycle current limit and

thermal shutdown to protect itself from fault

application.

Reverse current suppression for light load

Available in DFN10 (3X3) Packages

The A7130 is available in DFN10 (3X3) packages.
