ON Semiconductor Unveils New CS5305 Controller
ON Semiconductor (El Segundo, CA) announced the CS5305, a new three-phase, step-down controller, compliant with Intel’s latest voltage regulator module(VRM) specification.
With single-wire current sharing capability and feature-rich architecture, the CS5305 saves board space, simplifies CPU power supply design for high-performance microprocessors, and lowers overall design and manufacturing cost, according to the company.
The CS5305 uses enhanced V2 control architecture to accurately balance the current in each phase. The operating switching frequency can be set from 200kHz to 800 kHz.
"We designed the CS5305 to meet the strict specification of advanced computing architectures and Intel is currently using the device for its industry-leading Pentium processor platform," said Dale Carlton, ON Semiconductor’s director of the Computer Internet Business Unit. "Enhanced V2 enables the CS5305 to meet standard VRM 9.1 specifications with ease, achieving thermal efficiencies greater than 80 percent, operating at up to 80A, and improved transient response with a single, affordable chip."
ON Semiconductor offers the CS5305 in the 28-lead SO package. The suggested retail price for the CS5305 is $4.97 for 10,000-unit quantities.
