General Description Features

•

3.2A Output Current

The TD1484A is a monolithic synchronous buck

regulator. The device integrates two 90mΩ

MOSFETs, and provides 3.2A of continuous load

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

Wide 4.75V to 23V Operating Input Range

Integrated 90mΩ Power MOSFET Switches

Output Adjustable from 0.923V to 20V

Up to 93% Efficiency

•

Current mode control provides fast

response and cycle-by-cycle current limit.

transient

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-PP package,

provides a very compact solution with minimal external

components.

Applications

•

Distributed Power Systems

Networking Systems

•

FPGA, DSP, ASIC Power Supplies

Green Electronics/ Appliances

Notebook Computers
