ETA1657 18V, 5A, High Efficiency Synchronous Step-Down Converter in DFN2x2-6
■ETA1657 is a wide input range, high efficiency and high frequency DC to DC step-down switching regulator, capable of delivering up to 5A 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, ETA1657 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.
■ETA1657 is available in a DFN2x2 -6 package
●FEATURES:
■Wide Input Range: 4.5V-18V
