TX6212 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 Device ground / signal return.
2 EN input Chip enable, active high. Also accepts a PWM signal for LED dimming. Logic thresholds: VIH ≥ 0.4*VDD, VIL ≤ 0.8V. Abs-max: -0.3V to VDD+0.3V.
3 COMP output Error-amplifier output / loop compensation pin. Connect an external RC network to GND to set loop bandwidth and stability. Abs-max: -0.3V to VDD+0.3V.
4 FB input Output LED current-sense feedback input. Regulates to VFB = 250 mV (240-260 mV) across the external sense resistor RFB in the LED return path; ILED = 0.25 V / RFB. Abs-max: -0.3V to VDD+0.3V.
5 SW output Drain of the internal 100V power NMOS switch. Connects to the boost inductor and rectifier. VDS max = 100 V, RDS(on) ≈ 120 mΩ at VGS = 5 V. The exposed pad (heat slug) is internally tied to SW.
6 CS input Input peak inductor-current sense input. Sets peak-current limit via external RCS to GND; over-current threshold VCS_TH = 250 mV (240-260 mV), giving IPK ≤ 0.25 V / RCS. Abs-max: -0.3V to VDD+0.3V.
7 TOFF passive Off-time programming pin. Connect a capacitor COFF to GND: TOFF = 0.51 * 150 kΩ * (COFF + 7.3 pF) + 61 ns. With no external cap, off-time defaults to ~620 ns (min). Typical COFF is 22-33 pF or larger. Abs-max: -0.3V to VDD+0.3V.
8 VDD power_in Chip supply pin fed from VIN through an external dropping resistor RVDD. Internally clamped by a VDD Zener to ~5.5 V (IVDD < 10 mA); UVLO rising = 3.2 V with 0.5 V hysteresis. Bypass with a local ceramic capacitor to GND.
