CN5711 from ShangHai Consonance Elec, in a ESOP-8. 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	ISET	input	LED current setting pin. A resistor RISET between ISET and GND programs the LED constant current: ILED [A] = 1800V / RISET [ohm]. RISET maximum value is 30 kOhm. Keep resistor close to the pin and minimize parasitic capacitance.
2	GND	power_in	Negative terminal of the power supply (ground return).
3	VCC	power_in	Positive terminal of power supply, 2.8V to 6V (absolute max 6.5V). Powers the internal circuitry. Pins 3 and 4 are internally connected and must be tied together at the input supply.
4	VCC	power_in	Positive terminal of power supply, 2.8V to 6V (absolute max 6.5V). Pins 3 and 4 are internally connected and must be tied together at the input supply.
5	LED	output	LED anode drive pin (regulated current output). The internal power MOSFET sources up to 1.5A of constant current out of this pin into the LED anode. Pins 5 and 6 are internally connected and should be tied together for full current handling. Low dropout: 0.37V @ 1.5A.
6	LED	output	LED anode drive pin (regulated current output). Pins 5 and 6 are internally connected and should be tied together for full current handling.
7	NC	unconnected	No connection. Leave floating.
8	CE	input	Chip Enable input (TTL/CMOS compatible). High (>= 2.3V) enables normal operation; low (<= 0.6V) puts the device into shutdown (IVCC2 <= 1uA). Can also be driven with a PWM signal (<2 kHz) for LED dimming.
9	EP	power_in	Exposed thermal pad on the backside of the eSOP-8 package. Must be soldered to the PC board ground for proper thermal dissipation; failure to make good thermal contact increases thermal resistance and reduces maximum LED current.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn5711.step`	193 KB	You want the bare part, or you mark your own boards.
`cn5711-etched.step`	884 KB	You want the part with `CN5711` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 239 faces against 63 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.
