| Abstract |
Initially developed for CPU power supply, the Multi-Phase topology is now applicable also to highdensity
DC/DC converter. The Multi-Phase topology benefits input filter and components size
reduction resulting in power density increase that allows power supply size reduction too.
Implementing high power solutions by using more than one paralleled module, allows reducing both
their size and failure rate. Current sharing control among modules and hot pluggability contribute to
design a complete and robust uninterruptible solution.
This paper discusses the design of a high-current DC/DC converter module using a dual phase
controller L6712 and a current sharing controller L6615: it features Single-Wire Current Sharing Bus
among modules and hot-plug capability. |
