TPS62849DLCR 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. Connect this pin close to the GND terminal of the input and output capacitors. |
| 2 | VIN | power_in | VIN power supply pin. Connect the input capacitor close to this pin for best noise and voltage spike suppression. A 4.7-µF ceramic capacitor is required. |
| 3 | MODE | input | MODE pin. A low level enables Power-Save Mode operation with an automatic transition between PFM and PWM modes. A high level forces the converter to operated in PWM mode. This pin can be toggled during operation. It must be terminated. |
| 4 | EN | input | Enable pin. A high level enables the device and a low level turns the device off. The pin features an internal pulldown resistor, which is disabled once the device has started up and the output voltage is regulated. The pulldown resistor is activated again, once a low level has been detected. |
| 5 | VSET | input | Connecting a resistor to GND sets the output voltage when the converter is enabled. For the TPS62849, connect this pin to GND. |
| 6 | STOP | input | STOP Switching pin. When this pin is logic high, the converter stops switching to provide a quiet supply rail. The output is powered from the charge available in the output capacitor. When this pin is logic low, the device immediately resumes operation. The pin features an internal pulldown resistor, which is disabled once a high level is detected at the input. The pulldown resistor is activated again, once a low level has been detected. |
| 7 | SW | output | The switch pin is connected to the internal MOSFET switches. Connect the inductor to this terminal. |
| 8 | VOS | input | Output voltage sense pin for the internal feedback divider network and regulation loop. When the converter is disabled, this pin discharges VOUT by an internal MOSFET. Connect this pin directly to the output capacitor with a short trace. |
