WebMay 12, 2024 · A Flyback voltage or an Inductive Flyback is a voltage spike created by an inductor when its power supply is removed abruptly. The reason for this voltage spike is the fact that there cannot be an instant change to the current flowing through an Inductor. WebApr 1, 2024 · And I am trying to calculate the inductor value for it. Input Voltage = 9.5V to 16V LED string = 9 LEDs (each Vf of 3.1V and If=0.3A) Output voltage = 30V Output Current = 300mA In this case, I have been following the design example from page 35. I have got to this point : Vout_typ = 30.64V & Vf_schottky=0.52V. simon school admitted students https://astcc.net
