This application note covers the design of a ±72-V unregulated power supply specifically for audio amplifiers. The power supply is an unregulated design with an option to allow connection to either 120-V or 240-V mains. The design uses toroidal transformers, a fully integrated bridge, and various rail capacitors for

For simplicity, good performance, and reasonable cost, an unregulated supply is the most common for an audio power amplifier. An unregulated supply uses a transformer, a bridge rectifier, and various rail capacitors. A draw back to the unregulated supply is the voltage fluctuations with load and power mains fluctuations.

Output power is 32.2V × 1.61A = 51.8W, and the input is 28V × 2.98A = 83 VA. Input power is harder to measure and is the sum of the output power and all systems losses. For this example, we'll assume that the sum of the losses is 10W, so input power will be 62W.
