The VOUT_MIN and VOUT_MAX commands set the minimum and maximum allowed output voltage targets. TPS53676 does not ramp the output voltage target for either channel outside these limits for any reason. This includes being commanded to do so by VOUT_COMMAND, VOUT_MARGIN_HIGH, VOUT_MARGIN_LOW or VOUT_TRIM.

Whenever the output voltage target is commanded outside the limits set by VOUT_MIN and VOUT_MAX, the TPS53676 device detects the VOUT_MIN_MAX warning condition. In response, the device begins ramping the output voltage target of that channel to the new target and clamps to the VOUT_MIN or VOUT_MAX value. An example is shown in Figure 7-30.
