TX6133 from XDS, in a ESOP-8. 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 | GND | power_in | Ground pin for the LED constant-current driver; the current-sense resistor R2 should connect to CS and GND with short, thick traces to limit parasitic resistance error. |
| 2 | VDD | power_in | Chip supply pin fed through resistor R1 from the input, with an internal VDD clamp of 5.8 V typical (I_VDD < 10 mA) and UVLO at 4.1 V rising with 0.4 V hysteresis; the clamp current must not exceed 10 mA. |
| 3 | NC | unconnected | Not internally connected; leave floating. |
| 4 | SW | output | Switching node connected to the internal power MOSFET drain, rated up to 100 V. |
| 5 | CS | input | Current-sense input referenced to GND, with a sense threshold VCS of 192 mV min, 200 mV typical and 208 mV max that sets the average LED current. |
| 6 | HL | input | High/low brightness select: a high level gives half-brightness (1/2 current), while floating or grounded gives full brightness; an internal pull-down of 80 kΩ (typ) is present, and the HL/CS absolute voltage range is -0.3 V to VDD ±0.3 V. |
| 7 | NC | unconnected | Not internally connected; leave floating. |
| 8 | NC | unconnected | Not internally connected; leave floating. |
| 9 | EP | passive | Exposed heat-sink pad internally connected to the SW pin (MOSFET drain) for thermal dissipation. |
