ETA2841

42V Input Standoff Voltage, 0.6A Step-Down Converter in SOT23-6

DESCRIPTION

FEATURES

Wide Input Operating Range from 4V to 38V

The ETA2841 is a wide input range, high-efficiency, and high

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

capable of delivering up to 0.6A of output current. With a

fixed switching frequency of 650KHz, 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.ETA2841 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. An OVP function protects the IC itself

and its downstream system against input voltage surges.

With this OVP function, the IC can stand off input voltage as

high as 42V, making it an ideal solution for industrial

applications such as smart meters as well as automotive

applications.

Standoff Input Voltage: 42V

High Efficiency at 12V In 5V Out: Up to 91%:

High Efficiency PFM mode at light load

Capable of Delivering 0.6A

No External Compensation Needed

Current Mode control

Logic Control Shutdown

Thermal shutdown and UVLO

Available in SOT23-6 Package

APPLICATIONS

Smart Meters

Industrial Applications

Automotive Applications

In automotive systems, power comes from the battery, with

its voltage typically between 9V and 24V. Including cold

crank and double battery jump-starts, the minimum input

voltage may be as low as 4V and the maximum up to 36V,

with even higher transient voltages. With these high input

voltages, linear regulators cannot be used for high supply

currents without overheating the regulator. Instead, high

efficiency switching regulators such as ETA2841 must be

used to minimize thermal dissipation.
