A Power Management Interface Circuit for Telecom Hot Swap with Local DC/DC Conve
PDF, 467 Kb, File published: Apr 16, 2001
Today, the brains of telecom and datacom systems - i.e., microprocessors, DSPs, ASICs, and programmable logic - are evolving to ever-lower operating voltages. Typical ICs run at supply levels of 3.3 V, 2.5 V, and even lower. As this occurs, new devices and modules are being developed to address the functions of hot-swapping the standard ?48 Vdc bus, and subsequent conversion to local regulation l

Simplified Solutions for Hot Swap Power Management in Telecom Systems
PDF, 101 Kb, File published: Jul 20, 2001
Engineers designing plug-in or adapter cards for the ?48-Vdc distribution environment often need an efficient, cost-effective means of implementing hot swap capability. Hot swap solutions vary in complexity, some adding features for system or operator control and interface or other related functions. However, it is ultimately the basic function of applying input power to the module?s bulk capacita
