TPS62841DLCR from Texas Instruments, in a VSON-8(1.5x2). 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 | GND supply pin that must be connected close to the GND terminal of the input and output capacitors. |
| 2 | VIN | power_in | VIN power supply pin with a 1.8 V to 6.5 V supply range; the input capacitor must be placed close to this pin and a 4.7-µF ceramic capacitor is required. |
| 3 | MODE | input | A low level enables Power-Save Mode with automatic PFM/PWM transition and a high level forces PWM mode; the pin can be toggled during operation and must be terminated. |
| 4 | EN | input | Enable pin where a high level enables the device and a low level turns it off, with an internal pulldown resistor that is re-activated once a low level is detected. |
| 5 | VSET | input | Connecting a resistor to GND sets the output voltage when the converter is enabled, and parasitic capacitance to GND at this pin must stay at or below 100 pF; for the TPS62849 connect it to GND. |
| 6 | STOP | input | STOP switching pin where a logic high stops converter switching to provide a quiet supply rail powered from the output capacitor, and a logic low immediately resumes operation; it has an internal pulldown resistor. |
| 7 | SW | power_out | Switch pin connected to the internal MOSFET switches, where the inductor must be connected. |
| 8 | VOS | input | Output voltage sense pin for the internal feedback divider and regulation loop that must be connected directly to the output capacitor with a short trace, and it discharges VOUT through an internal MOSFET when the converter is disabled. |
