TX6210 from XDS, 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	GND	power_in	Chip ground reference. Return for analog and power circuitry.
2	EN	input	Enable input, active high (VIH ≥ 3.1V, VIL ≤ 1.1V). Can also accept a PWM signal for LED dimming.
3	COMP	output	Error amplifier output / frequency compensation node. Connect an external R-C network from COMP to GND to set loop compensation.
4	FB	input	Output LED current feedback input. Regulated to VFB = 250mV (typ, 240-260mV); LED current is set by ILED = 0.25V / R_FB.
5	SW	output	Drain of the internal 60V power NMOS switch. Connect to the boost inductor / rectifier diode; VSW rated to 60V max. The exposed pad is internally tied to this node.
6	CS	input	Input current-limit / peak inductor-current sense input. Threshold VCS_TH = 250mV (typ); maximum peak current set by IPK ≤ 0.25V / R_CS.
7	TOFF	input	Off-time setting pin. Connect capacitor C_OFF to GND; TOFF = 0.51 × 150kΩ × (C1 + 7.3pF) + 61ns. If left open, internal off-time defaults to 620ns.
8	VDD	power_in	Chip supply input, internally clamped by a zener to ~5.5V (I_VDD < 10mA). Typically fed from VIN through a series resistor R1 = (VIN - VDD) / I_VDD; UVLO ~3.6V rising, 0.3V hysteresis.
9	EP	passive	Exposed thermal pad on the ESOP-8 package. Internally connected to SW (pin 5); connect to the SW copper plane for heat dissipation.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tx6210.step`	193 KB	You want the bare part, or you mark your own boards.
`tx6210-etched.step`	1.1 MB	You want the part with `TX6210` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 288 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.
