FUNCTION
Connect to VL for output tracking. Connect to GND for output staggered sequence.
SEQ
18
18
Staggered sequence ramps up V OUT2 and V OUT3 softly to avoid glitches on the previous
voltage due to charging of the LDO’s output capacitors.
Shutdown Control and Synchronization Input. There are three operating modes:
? When SYNC/EN is low, the controller is off but the VL regulator is still running.
SYNC/EN
19
19
? When SYNC/EN is high, the controller is enabled with the switching frequency set by
R FREQ .
? When SYNC/EN is driven by an external clock, the controller is enabled and switches at
the external clock frequency.

No Connection. Not internally connected. Connect to GND or leave floating.
OUT3N Base-Drive Supply. Connect SUP3N to any positive voltage between 1.5V and 5.5V
to provide power for the negative linear-regulator transistor driver.
OUT3P Base Drive. Connect DRV3P to the base of an external PNP pass transistor to form a
positive linear voltage regulator.
OUT3N Base Drive. Connect DRV3N to the base of an external NPN pass transistor to form
a negative linear voltage regulator.
Main Voltage Input (4.5V to 28V). Bypass IN to GND, close to the IC, with a minimum 1μF
ceramic capacitor (C2). IN powers the linear regulator whose output is VL.
Power-On Reset. Open-drain output that goes high after all outputs reach the regulation
limit and a 315ms delay time has elapsed.
OUT3P Feedback Input. FB3P is referenced to 0.8V and connects to a resistive-divider
(R13, R14) to control a positive linear voltage regulator.
OUT3N Feedback Input. Connect a resistive-divider (R13, R14) from OUT1 to FB3N to
OUT3N to regulate FB3N to 0V.
ILIM Set Input. Connect a resistive-divider (R17, R18) from OUT1 to ILIM to GND. See the
Current Limit section.
Positive Current-Sense Input. Used to detect OUT1 current limit.
Negative Current-Sense Input. Used to detect OUT1 current limit.
Analog Soft-Start Control Input. This pin goes into the positive input of the VOUT1’s error
SS

amplifier. When the MAX8513/MAX8514 are turned on, SS is at GND and charges up to 1.25V
with a constant 25μA. Connect a capacitor (C13) from SS to GND for the desired soft-start time.
