Ultrathin Dual 2.5A or Single 5A ВµModule Regulator Fits on the
Backside of PCBs, Allowing Space on the Topside for Digital ICs
Design Note 546
Sam Young, Afshin Odabaee
Introduction
The top side of a typical system board, such as a
PCIe card, is densely populated with FPGAs/ASICs/
microprocessors, transceivers, connectors, memory
ICs and DC/DC regulators, while the backside is often
unused. This is a common side effect of the significant
difference in top vs back side height restrictions,
where board specifications may allow topside devices
to reach a few centimeters, but restrict backside
packages to less than 2.3mm. What if functions
usually found on the topside, such as DC/DC regulator
circuits could be thinner and moved to the bottom?
Real estate on top would be available for expanding
memory or enhancing the board/given the additional
top side space. Flexible Dual Supply in a Simple …
