In a boost converter, what is the factor that determines whether the power supply (dc-dc converter) will be in the CCM, BCM or DCM mode?
Because, I have an LED Driver A80604. 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. Vbat = 9.5V, 13.5V & 16V (Min, typ and Max)
Are my above calculations, right?
What is the factor that determines whether the power supply (dc-dc converter) will be in the CCM, BCM or DCM mode?
What is the required inductor value that I need to choose for this application which requires constant current for the LEDs?
