DC-DC CONVERTER BUCK (STEP-DOWN)

500kHz, 16V, 2A SYNCHRONOUS

DESCRIPTION

FEATURES

The A7222A is a fully integrated, high-efficiency 2A

synchronous rectified step-down converter. The

A7222A operates at high efficiency over a wide

output current load range.



High Efficiency: Up to 96%

500kHz Frequency Operation

2A Output Current

No Schottky Diode Required

This device offers two operation modes, PWM

control and PFM Mode switching control, which

allows a high efficiency over the wider range of the

load.

4.5V to 16V Input Voltage Range

0.6V Reference

Slope Compensated Current Mode Control for

Excellent Line and Load Transient Response

Integrated internal compensation

Stable with Low ESR Ceramic Output

Capacitors

The A7222A is available in SOT-26 package.
