钰泰 ETA3452S2G 新型高频同步降压转换器IC

　　DESCRIPTION

　　ETA3452 belongs to a new breed of high frequency synchronous Step-Down converters 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 ETA3452 also provides more superior load transient response and a seamless transition from PFM to PWM modes.ETA3452 is capable of supplying output with current up to 3A at 1.2V output. All these features make ETA3452 an excellent choice for ARM based CPU power supply.
