Efficient processor power system needs no heat sink
John Seago
Abstract
The LTC1435, a current mode, constant frequency, synchronous step-down switching regulator that uses external N-channel MOSFETs for very high efficiency, is described.

New designs require more functionality in an ever decreasing package size. Compact, efficient high frequency power supplies are required and there is seldom room for a heat sink. Portable computers have some of the most demanding requirements. Powering the Pentium processor adds additional challenges for the power system designer.
