ETA1753

18V, 3A, 1MHz High Efficiency Synchronous Step-Down Converter

in SOT563

DESCRIPTION

FEATURES

ETA1753 is a wide input range, high-efficiency and 1MHz

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

capable of delivering up to 3A of output current. It adopts

an Adaptive COT control scheme that enables very fast

transient response and provides a very smooth transition

when the output varies from light load to heavy load. During

light load, ETA1753 goes into a PFM mode that saves

switching loss achieving high efficiency. The adaptive COT

control also maintains a constant switching frequency

across line and load. 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 25V, making it an ideal solution for industrial

applications such as LCD TV, Set Top Box, Portable TV,

etc.
