FUNCTION
OVP Mode Control. This input selectively enables/disables the SMPS OV protection feature and
output discharge mode. When enabled, the SMPS OV protection feature is enabled. Connect OVP to
the following voltage levels for the desired function:
High (> 2.4V) = Enable SMPS OV protection, and SMPS and VTT discharge FETs.
Low (AGND) = Disable SMPS OV protection, and SMPS and VTT discharge FETs.
Open-Drain Power-Good Output. PGOOD1 is low when the SMPS output voltage is more than 15%
(typ) beyond the normal regulation point, during soft-start, and in shutdown.
After the soft-start circuit has terminated, PGOOD1 becomes high impedance if the SMPS output is
in regulation.
Open-Drain Power-Good Output. PGOOD2 is low when the VTT output voltage is more than 10%
(typ) beyond the normal regulation point, in shutdown, in standby, and during soft-start.
After the SMPS soft-start circuit has terminated, PGOOD2 becomes high impedance if the VTT
output is in regulation.
Standby Control Input. When SHDN is high and STDBY is low, the MAX17000 enters a low-
quiescent current mode, putting the SMPS in ultra-skip operation and turning off the VTT output
(high-Z). This mode helps save converter power loss in computer standby operation.
When STDBY is high, normal SMPS operation resumes and the VTT output is enabled.
Sense Pin for Termination Supply Output. Normally connected to the VTT pin to allow accurate
regulation to V CSL /2 or the REFIN voltage.
Termination Reference Buffer Output. VTTR tracks V CSL /2 when REFIN is connected to V CC . VTTR
tracks V REFIN when a voltage between 0.5V to 1.5V is set at REFIN. Decouple VTTR to AGND with a
0.33 μF ceramic capacitor.
Power Ground for VTT. Connect PGND2 externally to the underside of the exposed pad.
Termination Power-Supply Output. Connect VTT to VTTS to regulate the VTT voltage to the VTTS
regulation setting.
Termination Power-Supply Input. VTTI is the input power supply to the VTT linear regulator.
Normally connected to the output of the SMPS regulator for DDR applications.
External Reference Input. REFIN sets the feedback regulation voltage (VTTR = VTTS = V REFIN ) of
the MAX17000.
Connect REFIN to V CC to use the internal V CSL /2 divider.
Connect a 0.5V to 1.5V voltage input to set the adjustable output for VTT, VTTS, and VTTR.
Feedback Input for SMPS Output. Connect to V CC for a fixed +1.8V output or to AGND for a fixed
+1.5V output. For an adjustable output (1.0V to 2.7V), connect FB to a resistive divider from the
output voltage. FB regulates to +1.0V.
Negative Input of the PWM Output Current-Sense and Supply Input for VTTR. Connect CSL to the
negative side of the output current-sensing resistor or the filtering capacitor if the DC resistance of
the output inductor is utilized for current sensing.
CSL is also the path for the internal 16
discharge MOSFET when V CC UVLO occurs with OVP
enabled.
Positive Input of the PWM Output Current Sense. Connect CSH to the positive side of the output
current-sensing resistor or the filtering capacitor if the DC resistance of the output inductor is
utilized for current sensing.
