ETA1657
18V, 5A, High Efficiency Synchronous Step-Down Converter
in DFN2x2-6
DESCRIPTION
FEATURES
ETA1657 is a wide input range, high efficiency and Wide Input Range: 4.5V-18V
high frequency DC to DC step-down switching Adaptive COT Control
regulator, capable of delivering up to 5A of output Ultra-Fast Load Transient Response
current. It adopts an Adaptive COT control scheme that
High Efficiency PFM Mode at Light Load
enables very fast transient response and provides Low Rdson Internal Power FETs
a very smooth transition when the output varies Capable of Delivering up to 5A
from light load to heavy load. During light load, Thermal Shutdown and UVLO
ETA1657 goes into a PFM mode that saves Available in DFN2x2-6
switching loss achieving high efficiency.
