EN_EXTLDO — 39 O TPS65072:
This pin is the active high, push-pull output to enable an external LDO. This pin will be set and reset during startup and shutdown by the sequencing option programmed. The output is pulled internally to the SYS voltage if HIGH.
The output is only used for sequencing options for Sirf Prima or Atlas 4 processors with DCDC_SQ[2..0] = 100 or DCDC_SQ[2..0] = 111.
EN_wLED — 47 I TPS65072, : This pin is the actively high enable input for the wLED driver. The wLED converter is enabled by the ENABLE ISINK Bit OR enable EN_wLED pin.

PB_OUT 24 24 O Open-drain output. This pin is driven by the status of the /PB_IN input (after debounce). PB_OUT=LOW if PB_IN=LOW
PGND3 30 30 — Power GND for DCDC3. Connect to PGND (thermal pad)
PGOOD 26 26 O Open-drain power good output. The delay time equals the setting for Reset. The pin will go low depending on the setting in register PGOODMASK. Optionally it is also driven LOW for 0.5 ms when PB_IN is pulled LOW for >15s.
