EUP3475A

3A, 28V, 1MHz Synchronous

Step-Down Converter

FEATURES

DESCRIPTION

Automatic Pulse Skipping Mode at Light Load

3A Continuous Output Current

110ns Minimum On Time

Integrated 135mΩ High Side Switch

Integrated 90mΩ Low Side Switch

Wide 4.5V to 28V Operating Input Range

Output Adjustable from 0.8V to 24V

Up to 95% Efficiency

The EUP3475A is

a 1MHz fixed frequency

synchronous current mode buck regulator. The device

integrates both 135mΩ high-side switch and 90mΩ

low-side switch that provide 3A of continuous load

current over a wide operating input voltage of 4.5V to

28V.The internal synchronous power switch increases

efficiency and eliminates the need for an external

Schottky diode. Current mode control provides fast

transient response and cycle-by-cycle current limit.

Programmable Soft-Start

<1μA Shutdown Current

At heavy load, the EUP3475A operates at a fixed

frequency Pulse-Width Modulation mode for

excellent stability and transient response. At light

load, the EUP3475A will operates at a Pulse-

Skipping mode to save power.

1MHz Fixed Switching Frequency

Thermal Shutdown and Over Current Protection

Input Under Voltage Lockout

Available in SOP-8 (EP) package

RoHS Compliant and 100% Lead(Pb)-Free

Halogen-Free

The EUP3475A features short circuit and thermal

protection circuits to increase system reliability.

Externally programmable soft-start allows for proper

power on sequencing with respect to other power

supllies and avoids input inrush current during startup.

In shutdown mode, the supply current drops below

1μA. The EUP3475A is available in SOP-8 package

with the exposed pad.
