ILIM12
FUNCTION
SMPS1 and SMPS2 Current-Limit Adjust Input. The positive current-limit threshold voltage is 0.052
times the voltage between TIME and ILIM over a 0.2V to 1.0V range of V(TIME, ILIM). The I MIN12
minimum current-limit threshold voltage in skip mode is precisely 15% of the corresponding
positive current-limit threshold voltage.
SMPS3 Current-Limit Adjust Input. Two-level current-limit setting for SMPS3. The I LX3MIN minimum
current-limit threshold in skip mode is precisely 25% of the corresponding positive current-limit
threshold.

BST3
Internal High-Side MOSFET Drain Connection for SMPS3. Bypass to PGND with a 10μF or greater
ceramic capacitor close to the IC.
Inductor Connection for SMPS3. Connect LX3 to the switched side of the inductor.
Boost Flying Capacitor Connection for SMPS3. An internal switch between V DD and BST3 charges
the flying capacitor during the time the low-side FET is on.
Active-Low Shutdown Control Input. This input cannot withstand the battery voltage. Connect to
V CC for normal operation. Connect to ground to put the IC into its 1μA max shutdown state. During
startup, the output voltage is ramped up to the voltage set by the SVC and SVD inputs at a slew rate
of 1mV/μs. In shutdown, the outputs are discharged using a 20
switch through the CSN_ pins for
the core SMPSs and through the OUT3 pin for the northbridge SMPS.
The MAX17480 powers up to the voltage set by the two SVI bits.

CPU I/O Voltage (1.8V or 1.5V). Logic thresholds for SVD and SVC are relative to the voltage at V DDIO .
SMPS2 Remote Ground-Sense Input. Normally connected to GND directly at the load. GNDS2
internally connects to a transconductance amplifier that fine tunes the output voltage—
compensating for voltage drops from the SMPS ground to the load ground.
Connect GNDS1 or GNDS2 above 0.9V combined-mode operation (unified core). When GNDS2 is
pulled above 0.9V, GNDS1 is used as the remote ground-sense input.
