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.
ETA3452 is in a SOT23-6 package.
