This video introduces an AC-to-DC Flyback switching power supply that converts universal 50Hz AC input (85-V to 260VAC) to dual-output (positive and negative) 15VDC to 0.5A (2*7.5W), which can be used in various applications, such as powering dual-supply op amps, amplifiers, and waveform generators circuits.
