Multiple-voltage electronics systems often requirecomplex supply voltage tracking or sequencing, whichif not met, can result in system faults or even permanentfailures in the fi eld. The design diffi culties in meetingthese requirements are often compounded in distributedpowerarchitectures where point-of-load (pol) DC/DCconverters or linear regulators are scattered across PCboard space, sometimes on different board planes. Theproblem is that power supply circuitry is often the lastcircuitry to be designed into the board, and it must beshoehorned into whatever little board real estate is left.Often, a simple, drop-in, fl exible solution is needed tomeet these requirements.

Advancements in board assembly, PCB layout anddigital IC integration have produced a new generationof densely populated, high performance systems. Theboard-mounted point-of-load (pol) DC/DC power suppliesin these systems are subject to the same demandingsize, high power and performance requirements asother subsystems. The rigorous new pol demands aredifficult to meet with traditional controller or regulatorICs, or power modules.

The latest generation of Texas Instruments (TI) boardmountedpower modules utilizes a pin interconnect technologythat improves surface-mount manufacturability.These modules are produced as a double-sided surfacemount(DSSMT) subassembly, yielding a case-less constructionwith subcomponents located on both sides of theprinted circuit board (PCB). Products produced in theDSSMT outline use the latest high-efficiency topologiesand magnetic-component packaging. This providescustomers with a high-efficiency, ready-to-use switchingpower module in a compact, space-saving package. Bothnonisolated point-of-load (pol) switching regulators andthe isolated dc/dc converter modules are being producedin the DSSMT outline.TI’s plug-in power product line offers power modules inboth through-hole and surface-mount packages. The surfacemountmodules produced in the DSSMT outline use asolid copper interconnect with an integral solder ball fortheir

由于更高的集成度、更快的处理器运行速度以及更小的特征尺寸，内核及I/O电压的负载点(pol)处理器电源设计变得越来越具挑战性。处理器技术的发展必须要和pol电源设计技术相匹配。对当今的高性能处理器而言,5年或10年以前使用的电源管理解决方案可能已不再行之有效。因此，当为德州仪器(TI)的DaVinci数字信号处理器(DSP)进行pol电源解决方案设计时，充分了解基本电源技术可以帮助克服许多设计困难。本文以一个基于TI电源管理产品的电源管理参考设计为例，讨论一系列适用于DaVinci处理器的电源去耦、浪涌电流、稳压精度和排序技术。
