G5762/G5762A

2A Step-down DC/DC

Features

General Description

2A Output Current

The G5762 is a monolithic step-down switch mode

regulator with a built in internal power MOSFET. It

achieves 2A continuous output current over a wide input

supply range with excellent load and line regulation.

0.15Ω Internal Power MOSFET Switch

Stable with Low ESR Output Ceramic Capaci-

tors

Up to 95% Efficiency

30µA Shutdown Mode

Fixed 385kHz Frequency

Thermal Shutdown

Cycle-by-Cycle Over Current Protection

Wide 6.5V to 24V Operating Input Range

Output Adjustable from 1.22V to 21.6V(G5762)

Output Adjustable from 0.92V to 21.6V(G5762A)

Available in SOP-8 Package

Current mode operation provides fast transient re-

sponse and eases loop stabilization.

Fault condition protection includes cycle-by-cycle cur-

rent limiting, output short circuit protection and thermal

shutdown. In shutdown mode the regulator draws

30µA of supply current. Programmable soft-start over-

writes the internal soft-start for various requirement of

output power up ramp and minimizes the inrush supply

current at initial startup.

Applications

PC Monitors

DSL Modems

Distributed Power Systems

Pre-Regulator for Linear Regulators

The G5762 requires a minimum number of readily

available standard external components. It is available

in a SOP-8 package.
