Flyback input current
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. You can use Flyback transformers in many applications, including: 1. DC-DC power supplies 2. Telecom 3. LED Lighting 4. Power over Ethernet (PoE) 5. Capacitor charging 6. Battery charging 7. Solar Microinverters 8.
