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.
