AMD mode
Once L6714 receives all the correct supplies and enables, and AMD Mode has been
selected, it initiates the Soft-Start by stepping the reference from zero up to the programmed
VID code (
See Figure 14
); the clock now used to step the reference is the same as the main
oscillator programmed by the OSC pin, SSOSC pin is not applicable in this case. The Soft-
Start time results then (
See Figure 16
):
where T
SS
is the time spent to reach V
SS
and F
SW
is the main switching frequency
programmed by OSC pin. Protections are active during Soft-Start, UVP is enabled after the
reference reaches 0.6V while OVP is always active with the fixed 1.800V threshold (or the
programmed V
OVP
).
