Note 2: Limits are 100% production tested at T A = +25°C. Maximum and minimum limits over temperature are guaranteed by design
and characterization.
Note 3: The equation for the target voltage V TARGET is:
V TARGET = the slew-rate-controlled version of V DAC , where V DAC = 0V for shutdown, V DAC = V BOOT (IMVP-6.5) or V VID
(GMCH) during startup, and V DAC = V VID otherwise (the V VID voltages for all possible VID codes are given in Table 2).
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 can be
different due to MOSFET switching speeds.
