Modular and Configurable Power Supplies Streamline Design

Giulio Bocciolini, Product Marketing Manager Modular & Configurable Products, TDK-Lambda

In many applications, design engineers require multiple-output AC-DC solutions for their end equipment. Depending on the number of outputs required, there are three main options: multiple, single-output AC-DC power supplies, a distributed power architecture (DPA), or modular and configurable power supplies. Th
