ETA2848

42V Input Standoff Voltage, 0.4A Synchronous Step-Down Converter

DESCRIPTION

FEATURES

Wide Input Operating Range from 5V to 38V

The ETA2848 is a wide input range, high-efficiency,

synchronous step-down switching regulator, capable of

delivering up to 0.4A of output current. With a fixed switching

frequency of 700KHz, 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.ETA2848 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.

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 5V 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 ETA2848 must be used to

minimize thermal dissipation.
