ETA3485

1.5A, 2MHz Step-Down Converter in SOT23-5 Package

DESCRIPTION

FEATURES

The ETA3485 is a high-efficiency, DC-to-DC step-down  Up to 96% Efficiency

switching regulator, capable of delivering up to 1.5A of  Up to 1.5A Max Output Current

output current. The devices operate from an input  2MHz Switching Frequency

voltage range of 2.6V to 7V and provide output voltages  Light Load operation

from 0.6V to VIN, making the ETA3485 ideal for low  Internal Compensation

voltage power conversions. Running at a fixed  Tiny SOT23-5L Package

frequency of 2MHz allows the use of small inductance

value and low DCR inductors, thereby achieving higher

efficiencies. Other external components, such as

ceramic input and output caps, can also be small due

to higher switching frequency, while maintaining

exceptional low noise output voltages. Built-in EMI

APPLICATIONS

reduction circuitry makes this converter ideal power

supply for RF applications. Internal soft-start control

circuitry reduces inrush current. Short-circuit and

thermal-overload protection improves design reliability.
