Product Description  
When only VAUX (3.3V) is present, the device provides a  
low impedance direct connection (0.25TYP) from VAUX  
The CMPWR330 is a dual input regulator with a fully  
integrated VAUX switch capable of delivering up to  
400mA continuously at 3.3V. The output power is  
provided from three independent input voltage sources  
on a prioritized basis. Power is always taken in priority  
toVOUT  
.
All the necessary control circuitry needed to provide a  
smooth and automatic transition between all three  
supplies has been incorporated. This allows the VCC  
input supply to be dynamically switched without loss of  
output voltage.  
using the following order VCC, VSBY, and VAUX  
.
When VCC (5V) or VSBY is present, the device automati-  
cally enables the regulator and produces a stable 3.3V  
output at VOUT  
.
