Combining a flyback unit configuration with an innovative programmable technology helps facilitate the design of circuits intended for high-voltage applications in the analog/mixed-signal fields.

The process of choosing the proper flyback diode for the suppression circuit is quite simple. First, determine the current the clutch or brake demands.

The flyback converter topology includes an electromagentic interference filter and rectifier, a MOSFET switch, a rectifier diode, and an opto-isolator.

In Flyback converters, one of two drain-node clamp circuits are typically used to protect the MOSFET from the Flyback voltage spike: a Resistor, Capacitor and Diode (RCD), or a Zener diode.
