Description

The PKM series, developed in parallel with the PKJ series, provides the same levels of development in the smaller quarter-brick industry standard package featuring unparalleled power densities and efficiencies. These breakthrough performance features have been achieved by using the most advanced patented topology, utilizing integrated magnetics and synchronous rectification on a low resistivity mulitlayer PCB. The product features fast dynamic response times and low output ripple, which are important parameters when supplying low voltage logics. The PKM series is especially suited for limited board space and high dynamic load applications such as demanding microprocessors. The PKM series also offers over and under-voltage protection, over-temperature protection, soft-start and is short circuit proof.
