TPS62203DBVR

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

TPS62203DBVR 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 of the converter, which must stay within the 2.5 V to 6.0 V recommended input range.
2 GND power_in Ground pin of the device, which the enable and feedback levels are referenced to.
3 EN input Enable pin: pulling it to ground forces shutdown, pulling it to VI enables the device, and it must not be left floating.
4 FB input Feedback pin: connect directly to the output for the fixed-voltage version, or to an external resistor divider for the adjustable version.
5 SW bidirectional Switch pin connected to the internal MOSFET switches, where the inductor is connected.
