Powering Minds of the Smart

36V Input, 3.1A output Step-Down Converter in ESOP-8

DESCRIPTION

FEATURES

The ETA2822 is a total solution IC specifically for high voltage USB

charging applications. It includes a wide input range, high-

efficiency, and high frequency DC-to-DC step-down switching

regulator that is capable of delivering up to 3.1A of output current.

The DC-DC in ETA2822 is a current mode converter with a fixed-

frequency that is externally adjustable. There is also a cable

resistance compensation feature that allows users to adjust the

output voltage to compensate for the voltage drop due to cable

resistance.

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 power-meters as well

as automotive applications. In automotive systems, power comes

from the battery, with its voltage typically ranges 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, This makes ETA2822 ideal for the automotive application.

ETA2822 is housed in an ESOP8 package.
