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.
VoIP converters generally require power supply circuit topologies that are performance-driven (highly efficient with minimal conducted line current), easy to use and cost-effective with a small footprint and low profile. A number of topologies can be designed to meet these requirements to some degree.
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.
