DESCRIPTION
NO.

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
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
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
floating. A simultaneous logic-high level on EN and RUN enables the converter and a logic-low shuts down
the device.
Connect the inductor to this pin. This pin is connected to the source of the high-side MOSFET switch.
Connect the inductor to this pin. This pin is connected to the drain of the low-side MOSFET switch.
Power ground. Connect to AGND underneath the IC.
Positive output
Provides a bootstrapped supply for the rectifier MOSFET driver, enabling the gate of the MOSFET to be
driven above the output voltage.
Main output
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
divider between VGL and main output.
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
TPS65123.
Auxiliary linear regulator input. If this pin is connected to GND, the voltage regulator is disabled
(TPS65120/1/2). The low-dropout series-pass regulator (LDO) is enabled according to the GATE signal
timing.
Auxiliary linear regulator output (TPS65120/1/2).
Enable pin for negative output (TPS65124). This pin should be terminated and not be left floating.
Enable pin for positive output (TPS65124). This pin should be terminated and not be left floating.
