TPS62243QDDCRQ1

Texas Instruments · DC-DC Converters · SOT-23-5

TPS62243QDDCRQ1 from Texas Instruments, in a SOT-23-5. 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 VIN power_in VIN power supply pin; the recommended supply voltage range is 2 V to 6 V, and the absolute maximum input voltage is 7 V.
2 GND power_in GND supply pin.
3 EN input Enable pin: pulling it low forces the device into shutdown mode and pulling it high enables the device, and this pin must be terminated.
4 FB input Feedback pin for the internal regulation loop; connect the external resistor divider to this pin, or for the fixed-output-voltage option connect it directly to the output capacitor.
5 SW output Switch pin connected to the internal MOSFET switches; connect the inductor to this terminal.
