FUNCTION
AUX1 Controller Compensation Node. Connect a series resistor-capacitor from CC1 to GND to
compensate the converter control loop. This pin is actively driven to GND in shutdown, overload, and
thermal limit. See the AUX Compensation section.
AUX1 Controller Feedback Input. The feedback threshold is 1.25V. This pin is high impedance in
shutdown.
Step-Down Power Ground. Connect all PG_ pins together and to GND with short traces as close as
possible to the IC.
Step-Down Converter Switching Node. Connect to the inductor of the step-down converter. LXSD is high
impedance in shutdown.
Step-Down Converter Input. PVSD can connect to PVSU, effectively making OUTSD a boost-buck output
from the battery. Bypass to GND with a 1μF ceramic capacitor if connected to PVSU. PVSD can also be
connected to the battery but should not exceed PVSU by more than a Schottky diode forward voltage.
Bypass PVSD with a 10μF ceramic capacitor when connecting to the battery input. A 10k Ω internal
resistance connects PVSU and PVSD.
Step-Down Converter On/Off Control Input. Logic high = on; however, turn-on is locked out until the step-
up has reached regulation. This pin has an internal 330k Ω pulldown resistance to GND.
Step-Up Converter Compensation Node. Connect a series resistor-capacitor from CCSD to GND to
compensate the converter control loop. This pin is actively driven to GND in shutdown, overload, and
thermal limit. See the Step-Down Compensation section.
Step-Down Converter Feedback Input. Connect a resistive voltage-divider from OUTSD to FBSD to GND.
The FBSD feedback threshold is 1.25V. This pin is high impedance in shutdown.
AUX1 Controller On/Off Input. Logic high = on; however, turn-on is locked out until 1024 OSC cycles after
the step-up has reached regulation. This pin has an internal 330k Ω pulldown resistance to GND.
AUX2 Controller On/Off Input. Logic high = on; however, turn-on is locked out until 1024 OSC cycles after
the step-up has reached regulation. This pin has an internal 330k Ω pulldown resistance to GND.
AUX3 Controller On/Off Input. Logic high = on; however, turn-on is locked out until 1024 OSC cycles after
the step-up has reached regulation. This pin has an internal 330k Ω pulldown resistance to GND.
Step-Up Converter On/Off Control. Logic high = on. All other ON_ pins are locked out until 1024 OSC
cycles after the step-up DC-DC converter output has reached its final value. This pin has an internal
330k Ω pulldown resistance to GND.
Reference Output. Bypass REF to GND with a 0.1μF or greater capacitor. The maximum allowed load on
REF is 200μA. REF is actively pulled to GND when all converters are shut down.
Step-Up Converter Feedback Input. Connect a resistive voltage-divider from PVSU to FBSU to GND. The
FBSU feedback threshold is 1.25V. This pin is high impedance in shutdown.
Step-Up Converter Compensation Node. Connect a series resistor-capacitor from CCSU to GND to
compensate the converter control loop. This pin is actively driven to GND in shutdown, overload, and
thermal limit. See the Step-Up Compensation section.
