What is a 3G base station converter?

In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.

Are RF power amplifiers good for base station transceivers?

The performances of RF power amplifiers for base station transceivers results in a tradeoff between linearity, efficiency and gain. This tradeoff leads to an optimum quiescent current.

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.

How to choose a power supply topology for a multi-output DSL converter?

Selection criteria for the power supply topology in multi-output DSL converters include requirements for performance (high efficiency and tight load and line regulation), simplicity, low cost and a small footprint with a low profile. High performance is achieved by selecting the appropriate topology and control circuit.
