ETA1485
3A, 18V High Efficiency Synchronous Step-Down Converter
DESCRIPTION
The ETA1485 is a wide input range, high-efficiency,
DC-to-DC step-down switching regulator, capable of
delivering up to 3A of output current. Current mode PWM
control allows the use of small external components, such
as ceramic input and output caps, as well as small
inductors, while still providing low output ripples. On top of
the integrated internal synchronous rectifier that
eliminates external Schottky diode, ETA1485 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. Therefore, ETA1485 is a
much superior solution in comparison to other
competitions in terms of efficiency and cost. Overall,
ETA1485 is a highly efficient and robust solution for DC-DC
step-down applications that requires wide input ranges.
ETA1485 is available ESOP8 Packages.
