General Description Features

TD1482A

•

2A Output Current

The TD1482A is a monolithic synchronous buck

regulator. The device integrates two 130mΩ

MOSFETs, and provides 2A of continuous load current

over a wide input voltage of 4.75V to 23V. Current

mode control provides fast transient response

and cycle-by-cycle current limit.

Wide 4.75V to 23V Operating Input Range

Integrated 130mΩ Power MOSFET Switches

Output Adjustable from 0.923V to 20V

Up to 93% Efficiency

•

Programmable Soft-Start

An adjustable soft-start prevents inrush current at

turn-on, and in shutdown mode the supply current

drops to 1µA.

Stable with Low ESR Ceramic Output Capacitors

Fixed 340KHz Frequency

Cycle-by-Cycle Over Current Protection

Input Under Voltage Lockout

This device, availablein an SOP8

package,

provides a very compact solution with minimal external

components.

Applications
