NAME
ILIM12
FUNCTION
SMPS1 and SMPS2 Current-Limit Adjust Input. The positive current-limit threshold voltage is
precisely 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. Four-level current-limit setting for SMPS3. Also sets the offset
voltage for SMPS3.
The I LX3MIN minimum current-limit threshold in skip mode is precisely 25% of the corresponding
positive current-limit threshold.

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.
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 MAX17080 powers up to the voltage set by the 2 SVI bits.
