1/2/3-Phase Quick-PWM
IMVP-6.5 VID Controllers
ELECTRICAL CHARACTERISTICS (continued)
Note 3: The equation for the target voltage VTARGET is:
VTARGET = The slew-rate-controlled version of VDAC, where VDAC = 0 for shutdown
VDAC = VBOOT during IMVP-6.5 startup
VDAC = VVID otherwise (the VVID voltages for all possible VID codes are given in Table 4).
In pulse-skipping mode, the output rises by approximately 1.5% when transitioning from continuous conduction to no load.
Note 4: On-time and minimum off-time specifications are measured from 50% to 50% at the DH_ pin, with LX_ forced to 0V, BST_
forced to 5V, and a 500pF capacitor from DH_ to LX_ to simulate external MOSFET gate capacitance. Actual in-circuit times
might be different due to MOSFET switching speeds.
Note 5: Specifications to -40°C and +105°C are guaranteed by design, not production tested.
