Additional load current can slow down the output volt-
age change during a positive REFIN1 voltage change,
and can speed up the output voltage change during a
negative REFIN1 voltage change.
When the MAX17007/MAX17008 detect that the internal
target and REFIN1 are more than ±50mV (typ) apart,
the controller automatically blanks PGOOD1, blanks the

UVP protection, and sets the OVP threshold to max REF
+ 300mV. The blanking remains until 1) the internal tar-
get and REFIN1 are within ±30mV of each other, and 2)
an edge is detected on the error amplifier signifying
that the output is in regulation. This prevents the system
or internal fault protection from shutting down the con-
troller during transitions. Figure 11 shows the dynamic
REFIN transition (SKIP = GND) and Figure 12 shows
the dynamic REFIN1 transition (SKIP = REF).
