TPS92641PWPT from Texas Instruments, in a HTSSOP-16-EP. 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 | VIN | power_in | Input supply voltage from 7V to 85V operating range; bypass with 1-µF capacitor. |
| 2 | RON | input | Oscillator frequency setting pin; connect resistor to VIN and capacitor to GND. |
| 3 | UDIM | input | Undervoltage lockout and PWM dimming dual-function input with 1.276V threshold; connect resistor divider from VIN. |
| 4 | VOUT | input | Feedback input for regulated output voltage; connect scaled-down resistor divider from VOUT. |
| 5 | VREF | power_in | Precision 3V±2% system reference voltage with maximum 2.1mA source current; bypass with 100nF to 1µF capacitor. |
| 6 | IADJ | input | Analog current adjustment input; connect resistor divider from VREF or NTC thermistor to GND for thermal foldback. |
| 7 | COMP | output | Compensation network output; connect ceramic capacitor to GND for loop compensation. |
| 8 | SDIM | input | PWM dimming input for shunt FET dimming operation; internally pulled high when not driven. |
| 9 | SDRV | output | Shunt FET gate driver output; provides inverted signal to drive external parallel NFET across LED load. |
| 10 | GND | power_in | System ground return; connect to DAP for thermal relief via 6-9 vias. |
| 11 | CS | input | Current sense input; connect to positive terminal of sense resistor at bottom of LED stack. |
| 12 | LG | output | Low-side NFET gate driver output; use series resistor to limit slew rate and mitigate EMI noise. |
| 13 | VCC | power_out | Bias supply output for controller; bypass with 2.2µF to 3.3µF ceramic capacitor rated 10V minimum. |
| 14 | BOOT | power_out | Bootstrap supply output for high-side gate drive; connect 100nF ceramic capacitor and Schottky diode to VCC. |
| 15 | SW | output | Switch node output of buck regulator. |
| 16 | HG | output | High-side NFET gate driver output; use series resistor to limit slew rate and mitigate EMI noise. |
| 17 | DAP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
