SD6022A

SHOUDING · DC-DC Converters · SOT-23-6

SD6022A from SHOUDING, in a SOT-23-6. 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 AGND power_in Analog ground; connect all analog grounds to a common node and then to the power ground behind the output capacitors.
2 SW passive Switch node for output; connect the inductor between SW and VIN, with a maximum rating of -0.3V to 22V and 4.5A switch current, keeping traces short and wide to reduce EMI and overshoot.
3 VDD power_in Output voltage sense input and supply pin (operating range 2.5V to 5V; absolute maximum 6V), from which the NMOS switch gate drive is derived from the greater of VOUT and VIN.
4 EN input Logic-controlled shutdown input: high enables normal free-running operation, low shuts down (VENH 1V rising, VENL 0.6V), and it should be tied to VDD when VDD may reach 5.5V or above.
5 FB input Feedback input to the gm error amplifier; connect the resistor divider tap here (reference 1.212V typical, VOUT = 1.212V x [1 + R1/R2]).
6 PGND power_in Power ground.
