Hold-Up Value Calculator
Hold-up value Calculator
GAIA Converter proposes a hold-up calculator to determine the hold-up capacitor value, in the following configuration:
The capacitor value is calculated by the formula: C hold-up = 2 * P out * t / Eff * (V² cap - UVLO²), where
Note : PF is the Power fail voltage of the Hold-up module. This value can be tuned on HUGD300 only. In all cases PF should be greater or equals to UVLO.
