ETA3655 5A, 2MHz ADI Controlled Output Synchronous Step-Down Converter DESCRIPTION The ETA3655 is a high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 5A of pulse load. It integrates an ADI 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-OnTime control. Its adaptive Constant-On-Time control dynamically changes switch on time to achieve a constant switching frequency. It does not have the minimum ontime constrain normally a fixed-frequency current mode Step-down requires, allowing it to go down to very low duty ratio without affecting loop stability.
