IPC 9592B:2012 PDF Download

IPC 9592B:2012 is a standard that specifies the requirements for power conversion devices (PCDs) used in the computer and telecommunications industries. PCDs refer to devices such as ac to dc and dc to dc modules, converters, and power supplies. This standard focuses on the design, qualification testing, conformance testing, and manufacturing quality and reliability processes of PCDs.

The standard does not cover the functional requirements of specific equipment but rather sets the guidelines for the design and manufacturing of PCDs. It addresses PCDs that are used in the electronics industry to convert main power sources (typically ac) to lower dc voltages for direct use in electronic circuits or as secondary sources for additional dc to dc PCDs that provide various dc voltage levels for different electronic devices in a product.

Revision B of the standard includes updated performance evaluations, such as thermal and vibration tests, temperature cycling, shock and vibration tests, random vibration and free-fall drop tests. It also provides updated guidelines for component derating, covering a wide range of devices such as capacitors, resistors, diodes, transistors, transformers, inductors, microcircuits, circuit breakers, fuses, relays, switches, and oscillators. The revision also includes improved definitions for reliability terms, including the mean time between failure or MTBF. The standard is 126 pages long.
