8.2.4.8 Stability
All current-mode controlled regulators can suffer from an instability, known as subharmonic oscillation, if they operate with a duty cycle above 50%. To eliminate subharmonic oscillations, a minimum value of inductance is required to ensure stability for all boost and flyback regulators. The minimum inductance is given by:
Equation 6. 
where
- VSAT is the switch saturation voltage and can be found in the Characteristic Curves.
