ETA355E
5A, I2C Controlled Output Synchronous Step-Down Converter
DESCRIPTION
FEATURES
The ETA355E is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering 5A load, up to 6.5A of pulse load. It integrates an I2C interface that dynamically scales the output voltages on demand. The DCDC control block belongs to a new breed of high frequency synchronous Step-Down converter that combines the advantages of voltage mode control and Constant-On-Time control. Its adaptive Constant-OnTime control dynamically changes switch on time to achieve a constant switching frequency. It does not have the minimum on-time constrain normally a fixedfrequency current mode Step-down requires, allowing it to go down to very low duty ratio without affecting loop stability.
