XC9281/82

WORLD'S SMALLEST 600mA DC/DC

XC9281/82 5.5V 0.6A Step-Down DC/DC

Now with an even smaller solution, the XC9281/82 is an ultra-small synchronous step-down DC/DC which can operate from 2.5V~5.5V and deliver loads up to 600mA. Hi-SAT COT control supports ultra-fast load transient response performance and a stable 6MHz switching frequency.
