TERMINAL FUNCTIONS

I/O
DESCRIPTION
NAME
NO.
VIN
15
I
This is the input voltage pin of the device.
This pin can either be the gate driver output to an external small P-Channel MOSFET (see application
GATE
16
I/O
section), or an active high control input. Pulling GATE above the 1.4 V logic-high level and RUN to a logic-low
level disables the integrated active power-down sequencing.
RUN controls the external P-Channel MOSFET. This pin must be terminated and not be left floating. Forcing
RUN
2
I
this pin to a logic-high level turns on the external MOSFET switch.
This is the enable pin of the multiple-output dc-to-dc converter. This pin must be terminated and not be left

I
floating. A simultaneous logic-high level on EN and RUN enables the converter and a logic-low shuts down
the device.
SWN
14
I/O
Connect the inductor to this pin. This pin is connected to the source of the high-side MOSFET switch.
SWP
13
I/O
Connect the inductor to this pin. This pin is connected to the drain of the low-side MOSFET switch.
PGND
12
O
Power ground. Connect to AGND underneath the IC.
VGH
10
O
Positive output
Provides a bootstrapped supply for the rectifier MOSFET driver, enabling the gate of the MOSFET to be

driven above the output voltage.
VMAIN
8
I
Main output
FBH
9
I
Feedback pin for the positive output voltage divider. Regulates to 1.213 V nominal.
Feedback pin for the negative output voltage divider. Regulates to 0 V nominal. Connect feedback resistor
FBL
5
I
divider between VGL and main output.
FBM
6
I
Feedback pin for the main output voltage divider. Regulates to 1.213V nominal.
Analog ground. Connect to power ground (PGND) underneath IC. Pins 3 and 4 are only used for AGND in
AGND
7, 3, 4
TPS65123.
Auxiliary linear regulator input. If this pin is connected to GND, the voltage regulator is disabled

3
I
(TPS65120/1/2). The low-dropout series-pass regulator (LDO) is enabled according to the GATE signal
timing.
LDOOUT
4
O
Auxiliary linear regulator output (TPS65120/1/2).
ENVGL
3
I
Enable pin for negative output (TPS65124). This pin should be terminated and not be left floating.
ENVGH
4
I
Enable pin for positive output (TPS65124). This pin should be terminated and not be left floating.
