MT7714SH from MAXIC Tech, in a SOP-7. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	GND	power_in	Chip ground reference. Should be routed separately from the bus-capacitor ground per PCB guidance.
2	OVP	input	Output over-voltage protection setting pin with enable function. A resistor RSET to GND sets the OVP threshold (VOVP = 8.6·L·RSET/RCS). If pin voltage falls below the enable threshold (VOVP_EN typ 0.3 V, VOVP_SD typ 0.27 V) the output is shut down; leaving the pin floating disables OVP. RSET should be > 3 kΩ in normal use.
3	NC	unconnected	No connection. Leave floating.
4	HV	power_in	High-voltage supply pin for on-chip startup and internal supply (no external VCC cap or startup resistor needed). Chip begins operation when HV > 12 V and stops when HV < 7 V. Absolute-max sink current 5 mA.
5	DRAIN	power_out	Drain of the internal 500V high-voltage power MOSFET (BVDSS = 500 V). Pin 5 and pin 6 are tied to the same internal drain node. MT7714SH RDS(on) typ 2.5 Ω at VGS=10 V / IDS=1.5 A.
6	DRAIN	power_out	Drain of the internal 500V high-voltage power MOSFET (BVDSS = 500 V). Same net as pin 5.
7	CS	input	Current-sense input. Connect a sense resistor RCS to GND; internal comparator trips at VCS-TH = 400 mV (typ, 388-412 mV) to terminate the on-cycle. Sets LED current: ILED ≈ VCS-TH/(2·RCS). 350 ns leading-edge blanking. Absolute max -0.3 V to 6 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mt7714sh.step`	111 KB	You want the bare part, or you mark your own boards.
`mt7714sh-etched.step`	1.3 MB	You want the part with `MT7714SH` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 343 faces against 132 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
