What is a DC power system?
DC power system that helps meet the power requirements of telecom central office and mobile switching office applications. The power system can provide up to 20,000A output capacity in integrated, multi-cabinet configurations that implement three-phase three-wire rectifiers for commercial 208/240VAC or 480VAC power.
What is a preferred power supply architecture for DSL applications?
A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.
What is a low profile power supply?
Low profile power supply design usually includes printed circuit board (planar) power transformers and output inductors and surface mount input and output capacitors. Multiple output power supplies are often implemented with a multi-output flyback converter.
