TPS54202HDDCR

Texas Instruments · AC-DC Controllers and Regulators · TSOT-23-6

TPS54202HDDCR from Texas Instruments, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin. Source terminal of the low-side power NFET and ground return for the controller circuit. Connect sensitive VFB (feedback divider) return to this GND at a single point.
2 SW power_out Switch node connection between the internal high-side NFET and low-side NFET. Connects to the external inductor. Rated -0.3 V to 30 V (max), with -5 V allowed for 20-ns transients.
3 VIN power_in Input voltage supply pin, also the drain terminal of the high-side power NFET. Operating input range 4.5 V to 28 V (abs max 30 V). Bypass with a local ceramic capacitor close to the pin.
4 FB input Converter feedback input to the internal error amplifier. Connect to the output voltage through a resistor divider; internal reference is 0.596 V typ (0.581-0.611 V). Abs max -0.3 V to 7 V.
5 EN input Enable pin. Rising threshold ≈1.28 V, falling ≈1.25 V, with 1-µA hysteresis current at VEN = 1.5 V. Float the pin to disable the converter; drive high or tie to VIN through a resistor to enable. Abs max -0.3 V to 7 V.
6 BOOT power_out Bootstrap supply for the high-side NFET gate driver. Connect a 0.1-µF ceramic capacitor between BOOT and SW. BOOT-SW rated -0.3 V to 7 V (abs max).
