Digital Power-Supply Controller/Monitor
with PMBus Interface
Since the reference voltage input is provided by the
MAX8688, the REFIN mode provides complete control
of the POL in terms of soft-start, soft-stop, and margin-
ing transitions. It may be noted that the slew rates dur-
ing soft-start (t ON_RISE ) and during margining
(VOUT_TRANSITION_RATE) should be programmed
with POL current-limit consideration. An excessively
fast slew rate causes the POL to trip due to overcurrent.
A general guideline for setting the output-voltage slew
rate is as follows:
where C OUT is the output capacitance on the POL out-
put, I LOAD is the load current being delivered by the
POL, and I LIMIT is the current-limit setting of the POL.
On receipt of either an OPERATION OFF command or a
turn-off signal from A3/ONOFF, the MAX8688 com-
mences the shutdown operation that has been pro-
grammed for the POL being controlled. After the
programmed t OFF_DELAY time, the MAX8688 ramps
down the output voltage to zero precisely in the pro-
grammed t OFF_FALL time, and deasserts its open-drain
ENOUT output.
