ETA3515 - COT Synchronous Step-down Converter

Features

  • The ETA3515 is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. The device operates from an input voltage range of 2.5V to 5.5V and provides output voltages from 0.6V to VIN, making the ETA3515 ideal for low voltage power conversions. ETA3515 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, ETA35.

ETA3515 2MHz, 3A, COT Synchronous Step-down Converter in SOT563 DESCRIPTION FEATURES The ETA3515 is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. The device operates from an input voltage range of 2.5V to 5.5V and provides output voltages from 0.6V to VIN, making the ETA3515 ideal for low voltage power conversions. ETA3515 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, ETA3515 goes into a PFM mode that saves switching loss to achieve a high efficiency. The adaptive COT control also maintains a constant switching frequency across line and load.
