13 POWER_ON input Power_ON input for the internal state machine that must be pulled HIGH by the application processor to keep the system on after PB_IN is released; if released LOW, the DCDC converters and LDOs turn off when PB_IN is HIGH.

17 DEFDCDC3 input Select pin for the DCDC3 output voltage.
18 DEFDCDC2 input Select pin for the DCDC2 output voltage.
19 VDCDC1 input Feedback voltage sense input; for the fixed-voltage option it connects directly to Vout1, and for the adjustable version it connects to an external resistor divider, with an output range of 0.6 V to VINDCDC1.
20 L1 output Switch pin for DCDC1; connect to the inductor (1.5 µH to 2.2 µH recommended), with 600 mA maximum output current.

23 VDCDC2 input Feedback voltage sense input; connect directly to Vout2, with an output range of 0.6 V to VINDCDC2.
24 PB_OUT output Open-drain output driven by the status of /PB_IN after debounce; it goes LOW when PB_IN is LOW.
25 PB_IN input Enable input; when pulled LOW the DCDC converters and LDOs start with the internally programmed sequencing, with an internal 50 kΩ pull-up to AVDD6.
26 PGOOD output Open-drain power-good output whose delay equals the reset setting, going low per PGOODMASK and also driven LOW for 0.5 ms when PB_IN is pulled LOW for more than 15 s.
27 SDAT bidirectional Data line for the I2C interface.
28 SCLK input Clock input for the I2C interface.
29 VDCDC3 input Feedback voltage sense input; connect directly to Vout3, with an output range of 0.6 V to VINDCDC2.
30 PGND3 power_in Power ground for DCDC3; connect to PGND (thermal pad).
31 L3 output Switch pin for DCDC3; connect to the inductor (1.5 µH to 2.2 µH recommended), with 600 mA maximum output current for TPS65072.

38 FB_WLED input Feedback input for the boost converter output voltage, with an absolute maximum of 40 V.
39 EN_EXTLDO output TPS65072 only: active-high push-pull output that enables an external LDO, set and reset by the programmed sequencing option and pulled to SYS when HIGH.
40 INT output Open-drain interrupt output, generated by AC or USB voltage applied or removed and by PB_IN being pulled low (optionally high); the touch-screen event source does not apply to TPS65072.

48 INT_LDO output Connect a 2.2 µF bypass capacitor from this pin to GND; the pin is the output of an internal LDO that powers the touch-screen controller (TSREF), which TPS65072 does not provide.
49 Thermal Pad passive Exposed pad (from the footprint; not named in the datasheet pin table).

  • Symbol: TPS65072RSLR
  • Footprint: Package_DFN_QFN:QFN-48-1EP_6x6mm_P0.4mm_EP4.4x4.4mm
  • 3D model: VQFN-48-EP(6x6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: tps65072rslr-etched.step / tps65072rslr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps65072rslr.step / tps65072rslr.glb are the bare package body.
