ERROR AMPLIFIER
gM
Error amplifier transconductance
gmPS
COMP to ILX gm
POWER GOOD RESET GENERATOR
-2 µA < ICOMP < 2 µA
ILX = 0.5 A
VUVBUCKX
Threshold voltage for buck under
voltage
Output falling
Output rising (PG will be
asserted)
tUV_deglitch
tON_HICCUP
tOFF_HICCUP
Deglitch time (both edges)
Hiccup mode ON time
Hiccup mode OFF time
VUVBUCKX asserted
All converters disabled. Once
tOFF_HICCUP elapses, all
converters will go through
sequencing again.
VOVBUCKX
Threshold voltage for buck over
voltage
Output rising (high side FET will
be forced off)
Output falling (high side FET will
be allowed to switch )
tRP
minimum reset period
Measured after the later of
Buck1 or Buck3 power-up
successfully
