Efficiency vs. Output Current Comparison 

The XC9276’s ultra-low quiescent current contributes to a high level of efficiency at a light load currents and this, combined with the VSET function, makes the XC9276 a solution that really helps to extend battery life in battery powered applications.





Space Saving & Low Profile PCB Mounting Area 

With the ultra-small WLP-6-03 package (1.7 x 1.07 x 0.33mm) and a small and low profile 2.2µH inductor, the XC9276 is a space saving solution:
