TPS6282518DMQR

Texas Instruments · Global Sourcing Parts · VSON-6(1.5x1.5)

TPS6282518DMQR from Texas Instruments, in a VSON-6(1.5x1.5). 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 EN input Device enable pin that must be pulled high to enable the device, pulling it low disables the device, and it must not be left floating.
2 PG output Power-good open-drain output whose pullup resistor can be connected to voltages up to 5.5V, and which may be left floating if unused.
3 FB input Feedback pin that must be connected to the output for the fixed output voltage versions.
4 GND power_in Ground pin.
5 SW power_out Switch pin of the power stage.
6 VIN power_in Input voltage pin; for the TPS62825x and TPS62826x family the input voltage range is 2.4V to 5.5V.
