World's Smallest 600mA DC/DC Converter
The XC9281 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 4MHz or 6MHz switching frequency.
The XC9281B18E0R-G also features soft-start and an optional CL discharge function.
Available in LGA-6B01 and an ultra-small WLP-6-05 package, measuring only 0.96 x 0.88 x 0.33mm, an extremely small DC/DC circuit of only 3.52mm2 can be implemented with a minimal number of external components.
Because the XC9281 uses such small packages and external components, the PCB area and thus the length of the copper tracks is minimised which results in extremely low radiated noise and excellent EMI performance.
