MP8007HGV-Z from Monolithic Power Systems, in a QFN-28(4x5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 AUX input Auxiliary power input detector for adapter power supply applications; driving VDD-AUX above 2.3V disables the hot-swap MOSFET and CLASS pin function and forces T2P and PG to be active.
2 DET passive Connect a 24.9kΩ resistor between VDD and DET for PoE detection.
3 N/C unconnected Not connected internally; can be connected to the GND pin and exposed thermal pad in the layout.
4 VDD power_in Positive power supply terminal from the PoE input power rail.
5 FB2 input Feedback pin for the non-isolated buck solution; connect FB2 to VDD in flyback application mode.
6 MODE input Selects buck or flyback mode: float for buck application mode, connect to GND for flyback application mode; the pin is pulled up internally to VCC through a 1.5µA current source.
7 FB1 input Feedback for the flyback solution; connect FB1 to GND in buck application mode.
8 ILIM input DC/DC converter switching current limit program pin; connect to GND through a resistor to program the peak current limit.
9 AGND power_in Analog power return for the DC/DC converter control circuit; connect to GND through a single point.
10 VCC power_out Supply bias voltage powered through the internal LDO from VIN; a capacitor of no less than 1µF should be connected between VCC and GND.
11 N/C unconnected Not connected internally; can be connected to the GND pin and exposed thermal pad in the layout.
12 SW passive Drain of the converter switching MOSFET.
13 SW passive Drain of the converter switching MOSFET.
14 N/C unconnected Not connected internally; can be connected to the GND pin and exposed thermal pad in the layout.
15 N/C unconnected Not connected internally; can be connected to the GND pin and exposed thermal pad in the layout.
16 GND power_in Switching converter power return; connect to RTN for the PoE power supply.
17 GND power_in Switching converter power return; connect to RTN for the PoE power supply.
18 PG output PD supply power good indicator that enables the DC/DC converter internally; it is pulled up by an internal current source in output-high conditions and is recommended to be floated in application mode.
19 N/C unconnected Not connected internally; can be connected to the GND pin and exposed thermal pad in the layout.
20 RTN passive Drain of the PD hot-swap MOSFET; connect the RTN pin to GND and AGND.
21 RTN passive Drain of the PD hot-swap MOSFET; connect the RTN pin to GND and AGND.
22 N/C unconnected Not connected internally; can be connected to the GND pin and exposed thermal pad in the layout.
23 VSS power_in Negative power supply terminal from the PoE input power rail.
24 VSS power_in Negative power supply terminal from the PoE input power rail.
25 FTY passive Factory use only; connect FTY to VSS in application mode.
26 CLASS passive Connect a resistor from CLASS to VSS to program the classification current.
27 T2P output Type 2 PSE indicator; open-drain output that is pulled low to VSS to indicate the presence of a Type-2 PSE or when AUX is enabled.
28 N/C unconnected Not connected internally; can be connected to the GND pin and exposed thermal pad in the layout.
29 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
