WebApr 8, 2024 · A flyback is a simple DC-to-DC or AC-to-DC converter which consists of a transformer that stores the energy when the current is passing through the circuit and releases it when the power is removed. A flyback topology was chosen, keeping in mind its characteristics, to be used for both step-up and step-down operations. WebThe flyback converter is an isolated power converter. The two prevailing control schemes are voltage mode control and current mode control. In the majority of cases current mode control needs to be dominant for stability during operation. Both modes require a signal related to the output voltage. WebThe Power Integrations InnoSwitch4-CA is a family of Flyback Switcher ICs, marking a significant milestone for GaN technology.
