ETA2359

1.4MHz, 1.2A, 24V High Efficiency Step-Down Converter in SOT23-6

DESCRIPTION

. FEATURES

Wide Input Operating Range from 4.5V to 24V

High Efficiency:

Up to 94%

Capable of Delivering 1.2A

1.4MHz Switching frequency

No External Compensation Needed

Current Mode control

Logic Control Shutdown

Thermal shutdown and UVLO

Available in SOT23-6 Package

The ETA2359 is a wide input range, high-efficiency, high

frequency DC-to-DC step-down switching regulator,

capable of delivering up to 1.2A of output current. With a

fixed switching frequency of 1.4MHz, this current mode PWM

controlled converter allows the use of small external

components, such as ceramic input and output caps, as

well as small inductors, while still providing low output

ripples. Together with the tiny package ETA2359 is in,

without external compensation components, it is an ideal

solution for system designer with stringent board space

requirements. ETA2359 also employs a proprietary control

scheme that switches the device into a power save mode

during light load, thereby extending the range of high

efficiency operation.
