ACE732E 6V/3.5A, Fast Response, Step-Down Converter Description ACE732E 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-On-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 ACE732E also provides a more superior load transient response and a seamless transition from PFM to PWM modes. ACE732E is capable of supplying output with current up to 3.5A at 1.2V output.
