CS5305  
Three−Phase Synchronous  
Switching Step−Down  
Controller with Single  
Wire Current Sharing  
http://onsemi.com  
MARKING  
The CS5305 provides a low−cost, single−controller solution for the  
low−voltage, high−current power needs of next−generation  
workstation and server processors. This IC provides high accuracy and  
the industry’s fastest transient response, reducing the need for large  
banks of output capacitors and providing the most compact, reliable,  
and economical power supply.

CS5305  
Since each phase’s output voltage and current feed back to develop  
the PWM ramp signal (enhanced V ™ control), the CS5305 shares

output current accurately between phases. Accurate current sharing  
means that the power supply design does not need to use power  
components rated to handle mismatched current per phase. The

enhanced V control compensates for variations in both line and load.  
The IC’s built−in single wire current sharing capability allows easy  
paralleling of multiple Voltage Regulator Modules (VRMs) based on  
the CS5305. The paralleled VRMs use a shared bus to provide high  
current and high reliability to multiple microprocessor workstations  
or servers.

The CS5305 meets VRM 9.x specifications with its Power Good,  
Enable, Differential Remote Sense, and single−wire Current Share  
features. The product fits server and workstation VRMs, and can be  
used to power Embedded Processors. The IC provides the simplest,  
lowest−cost solution for any low voltage, high current power supply.
