TPS622314TDRYRQ1

Texas Instruments · DC-DC Converters · XSON-6(1x1.5)

TPS622314TDRYRQ1 from Texas Instruments, in a XSON-6(1x1.5). 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 MODE input MODE high forces the device into PWM operation, and MODE low enables Power Save Mode with automatic transition from PFM to PWM. The datasheet states that the pin must be held at a defined high or low level and recommends tying it high for noise-sensitive applications.
2 SW output Switch pin connected to the internal MOSFET switches; the inductor must be connected to this terminal. Absolute maximum voltage at SW is -0.3 V to 7 V.
3 VIN power_in Power supply pin; the input voltage range is 2.05 V to 6 V, with absolute maximum -0.3 V to 7 V.
4 GND power_in Ground supply pin for the device, to be connected to the common Power GND node per the layout guidance.
5 EN input Enable pin: pulling it low forces shutdown mode and pulling it high enables the device; the pin must be terminated and its voltage must not exceed VIN + 0.3 V (max 7 V).
6 FB input Feedback pin for the internal regulation loop; connect it directly to the output capacitor, with absolute maximum voltage of -0.3 V to 3.6 V.
