ETA1661
18V, 4A, High Efficiency Synchronous Step-Down Converter
in SOT563
DESCRIPTION
FEATURES
ETA1661 is a wide input range, high efficiency and high frequency DC to DC step-down switching regulator, capable of delivering up to 4A 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, ETA1661 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.
ETA1661 is available in a tiny SOT563 package.
Wide Input Range: 4.
