TPS62221DDCT

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

TPS62221DDCT 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 VI power_in Supply voltage pin, with a recommended range of 2.5 V to 6 V and an absolute maximum of 7.0 V.
2 GND power_in Ground pin, which is the network ground reference for all voltages on the device.
3 EN input Enable pin: pulling it to ground forces shutdown mode, pulling it to VIN enables the device, and the pin must be terminated.
4 FB input Feedback pin: connect directly to the output for fixed-voltage versions, or to an external resistor divider for the adjustable version.
5 SW bidirectional Switch pin connected to the inductor and the internal MOSFET switches, with voltage limits of -0.3 V to VI +0.3 V.
