Features, Applications

CS5305 Three-Phase Synchronous Switching Step-Down Controller with Single Wire Current Sharing

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. Since each phase's output voltage and current feed back to develop the PWM ramp signal (enhanced V2TM 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 V2 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.
