WebApr 15, 2024 · A: A flyback converter is a simple implementation of a switch-mode power supply (SMPS), and it can be designed to deliver a DC output from either an AC or DC input, with outputs both lower and higher than the supply source (buck/boost operation). WebThe second use case is as a single-stage flyback design for narrow-range systems with 120 V and 230 V input voltages. 800 V MOSFETs will probably remain the devices of choice for single-stage flyback designs. Rising cost pressures for some narrow-range designs may position 700 V as a cost-effective alternative to 800 V MOSFETs.
