ETA3428B

3A 3MHz Synchronous Step-Down DC-DC in DFN3X3-10

FEATURES

DESCRIPTION

High Efficiency: Up to 95%

Capable of Delivering 3A

The ETA3428B is a high-efficiency, DC-to-DC step-down

switching regulators, capable of delivering up to 3A of

output current. The device operates from an input voltage

range of 2.6V to 5.5V and provides an output voltage from

0.8V to VIN, making the ETA3428B ideal for low voltage

power conversions. External programmable frequency and

compensation network of the ETA3428B enable system

designers to make trade off according to different

requirements such as board space, output transient

response and efficiency. Internal soft-start control

circuitry reduces inrush current. Short-circuit and

thermal-overload protection improves design reliability.

ETA3428B is housed in a DFN-10 Package
