TPS92640PWPR from Texas Instruments, in a HTSSOP-14-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 | Connect to input voltage between 7V and 85V with 1-µF bypass capacitor. |
| 2 | RON | input | Connect resistor to VIN and capacitor to GND to set switching frequency. |
| 3 | UDIM | input | Connect resistor divider from VIN to set undervoltage lockout threshold or drive with PWM dimming signal. |
| 4 | VOUT | input | Connect resistor divider from VOUT to provide scaled feedback voltage for output regulation. |
| 5 | VREF | power_out | 3V ±2% reference voltage output with up to 2.1mA source capability; bypass with 100-nF ceramic capacitor. |
| 6 | IADJ | input | Current adjustment input with 2.54V maximum clamp for analog dimming level or thermal foldback operation. |
| 7 | COMP | output | Error amplifier output; connect ceramic capacitor to GND to set loop compensation. |
| 8 | GND | power_in | System ground reference; connect to thermal pad (DAP) for heat dissipation. |
| 9 | CS | input | Current sense input; connect to positive terminal of sense resistor at bottom of LED stack. |
| 10 | LG | output | Low-side NFET gate driver output; use series resistor to limit current slew rate and mitigate EMI noise. |
| 11 | VCC | power_out | 8.5V bias supply output for controller; bypass with 2.2-µF ceramic capacitor rated 10V or greater. |
| 12 | BOOT | power_out | Bootstrapped gate drive supply output; connect 100-nF capacitor to switch node and Schottky diode to VCC. |
| 13 | SW | output | Switch node output; connect to inductor and low-side NFET drain of buck regulator. |
| 14 | HG | output | High-side NFET gate driver output; use series resistor to limit current slew rate and mitigate EMI noise. |
| 15 | DAP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
