ACE732E

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. All these features make ACE732E an excellent choice for ARM based CPU power supply.
