Multiple Output Flyback Power Supply for Audio AmplifierThe universal input power supply shown in Figure above has multiple outputs, ±26 VDC, ±15 VDC, and +5 VDC. The ±26 V outputs can each deliver a minimum output current of 2.42 A peak (thermally limited) and 1.45 A continuous. Additionally, the voltage regulation and, importantly, transient response is excellent over the entire load range (no-load to full load).source
