ETA1655 - High Efficiency Synchronous Step-Down Converter

Datasheet Summary

Features

  • ETA1655 is a wide input range, high efficiency and high frequency DC to DC step-down switching regulator, capable of delivering up to 4.5A 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, ETA1655 goes into a PFM mode that saves switching loss achieving high efficiency. The adaptive COT control also maintains a constant switching freq.

ETA1655 18V, 4.5A, High Efficiency Synchronous Step-Down Converter in FCDFN2x2-6 DESCRIPTION FEATURES ETA1655 is a wide input range, high efficiency and high frequency DC to DC step-down switching regulator, capable of delivering up to 4.5A 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, ETA1655 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. ETA1655 is available in a FCDFN2x2-6 package.  Wide Input Range: 4.
