Dual-Phase, Quick-PWM Controllers for
IMVP-6+/IMVP-6.5 CPU Core Power Supplies
Detailed Description
Table 1 lists the component selection for standard
applications. Table 2 lists component suppliers for the
MAX17021/MAX17082/MAX17482/MAX17482.
Free-Running, Constant-On-Time PWM
Controller with Input Feed-Forward
The Quick-PWM control architecture is a pseudo-fixed-
frequency, constant-on-time, current-mode regulator
with voltage feed-forward (Figure 3). This architecture
relies on the output filter capacitor’s ESR to act as the
current-sense resistor, so the output ripple voltage pro-
vides the PWM ramp signal. The control algorithm is
simple: the high-side switch on-time is determined sole-
ly by a one-shot whose period is inversely proportional
to input voltage, and directly proportional to output volt-
age or the difference between the main and secondary
inductor currents (see the On-Time One-Shot section).
Another one-shot sets a minimum off-time. The on-time
one-shot triggers when the error comparator goes low,
the inductor current of the selected phase is below the
valley current-limit threshold, and the minimum off-time
one-shot times out. The controller maintains 180° out-of-
phase operation by alternately triggering the main and
secondary phases after the error comparator drops
below the output-voltage set point.
