Overview

ETA3451 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 ConstantOn-Time control dynamically changes switch on time to achieve a constant switching frequency. It does not have the minimum on-time constrain normally a fixed-frequency current mode Step-down requires, allowing it to go down to very low duty ratio without affecting loop stability. The voltage mode nature of ETA3451 also provides a more superior load transient response and a seamless transition from PFM to PWM modes. ETA3451 is capable of supplying output with current up to 3.5A at 1.2V output. All these features make ETA3451 an excellent choice for ARM based CPU power supply. ETA3451 is in a tiny DFN2x2-8 package.
