ETA1753 18V, 3A, 1MHz High Efficiency Synchronous Step-Down Converter in SOT563 DESCRIPTION ETA1753 is a wide input range, high-efficiency and 1MHz frequency DC-to-DC step-down switching regulator, capable of delivering up to 3A 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, ETA1753 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.
