3A, 18V SYNCHRONOUS, WIDE INPUT RANGE

STEP-DOWN CONVERTER

DESCRIP≤ION

FEA≤≥RES

≤he A7230 is a monolithic synchronous buck

regulator. ≤he device integrates 100mΩ MOSFE≤S

that provide 3A continuous load current over a wide

operating input voltage of 4.75V to 18V. Current mode

control provides fast transient response and

cycle-by-cycle current limit.



3A Output Current

Wide 4.75V to 18V Operating Input Range

Integrated 100mΩ Power MOSFE≤ Switches

Output Adjustable from 0.925V to 15V

≥p to 95% Efficiency

Programmable Soft-Start

Stable with Low ESR Ceramic Output Capacitors

Fixed 370KHz Frequency

An adjustable soft-start prevents inrush current at

turn-on. In shutdown mode, the supply current drops

below 1μA.

Cycle-by-Cycle Over Current Protection

Input ≥nder Voltage Lockout

Available in PSOP8 package

≤he A7230 provides a very compact system solution

with minimal reliance on external components.

APPLICA≤ION

≤he A7230 is available in PSOP8 Package.
