Once CSL or FB is in regulation, the PWM block turns off and enters standby mode.
VTT remains off throughout since STDBY is low. PGOOD2 stays low throughout. The VTT
discharge FET is enabled if OVP is high, but disabled if OVP is low.
VTTR ramps up to the final voltage based on V CSL /2 or V REFIN .
Ultra-skip and standby modes are exited and the full current capability of the MAX17000 is
available.

Ultra-skip or skip mode is exited as the MAX17000 ramps the output down to zero.
VTTR tracks V CSL /2 or V REFIN during shutdown. After the SMPS output reaches 25mV, DL goes low.
