4 FAQs about Does the design life requirement for base station power supply have high requirements

What are safety standards for power supplies?

Safety standards for power supplies relate to not only the power supply itself but the complete product, and there may be regional variations or adaptations of the standard's specification. Critical safety criteria include isolation techniques and leakage currents.

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 are the characteristics of a power supply?

International standards exist that stipulate several key power supply attributes. These include power efficiency, no-load power consumption, safety parameters such as isolation voltages, and electromagnetic interference (EMI).

How much power does a PSU need?

This is when the PSU is no longer powering the PA, which is the main power draw, but still needs to power other electronics. The current target for low-load efficiency is about 30 W. Some OEMs would like to see that drop to nearly 10 W.
