1. This value is useful to define the voltage rating for external capacitor to be connected from V
2. This typical value is only intended to give an estimation of the current consumption when L6460 is configured in simple
3. Measured between 10% and 90% of output voltage transition.
4. Measured from a fault detection to 50% of output voltage transition.
5. Current is defined to be positive when flowing into the pin.
6. Load regulation is calculated at a fixed junction temperature using short load pulses covering all the load current range. This
