Output-Voltage Transition Timing
The MAX17410 performs mode transitions in a controlled
manner, automatically minimizing input surge currents.
This feature allows the circuit designer to achieve nearly
ideal transitions, guaranteeing just-in-time arrival at the
new output voltage level with the lowest possible peak
currents for a given output capacitance.
At the beginning of an output voltage transition, the
MAX17410 blanks both PWRGD thresholds, preventing
the PWRGD open-drain output from changing states
during the transition. The controller enables the lower
PWRGD threshold approximately 20 μ s after the slew-
rate controller reaches the target output voltage, but the
upper PWRGD threshold is enabled only if the controller
remains in forced-PWM operation. If the controller enters
pulse-skipping operation, the upper PWRGD threshold
remains blanked. The slew rate (set by resistor R TIME )
must be set fast enough to ensure that the transition
may be completed within the maximum allotted time.
The MAX17410 automatically controls the current to the
minimum level required to complete the transition in the
calculated time. The slew-rate controller uses an internal
capacitor and current-source programmed by R TIME to
transition the output voltage. The total transition time
depends on R TIME , the voltage difference, and the
accuracy of the slew-rate controller (C SLEW accuracy).
The slew rate is not dependent on the total output
capacitance, as long as the surge current is less than
the current limit. For all dynamic VID transitions, the
transition time (t TRAN ) is given by:
- V
( dV TARGET / dt )
where dV TARGET /dt = 12.5mV/μs × 71.5k Ω /R TIME is the
slew rate, V OLD is the original output voltage, and V NEW
is the new target voltage. See the time slew-rate accu-
racy in the Electrical Characteristics table for slew-rate
limits. For soft-start and shutdown, the controller auto-
matically reduces the slew rate to 1/8th.
The output voltage tracks the slewed target voltage,
making the transitions relatively smooth. The average
inductor current per phase required to make an output
voltage transition is:
