ACE732E

6V/3.5A, Fast Response, Step-Down Converter

VER 1.2

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.
