The XC9281/82 by TOREX, 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. The series also features soft-start and an optional CL discharge function. The PWM/PFM auto switching XC9282's quiescent current is just 11µA. Available in LGA-6B01 and an ultra-small WLP-6-05 package, an extremely small DC/DC circuit of only 6.6mm2 can be implemented. Because of this, the PCB area and the length of the copper tracks is minimized which results in extremely low radiated noise and excellent EMI performance.
