SD6410

SHOUDING · DC-DC Converters · SOT-23-5

SD6410 from SHOUDING, 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	RUN	input	Chip enable pin; drive above 1.5V to turn the part on and below 0.3V to turn it off, and do not leave it floating.
2	GND	power_in	Ground pin.
3	SW	output	Power switch output and switch node connection to the inductor, connected to the drains of the internal P-ch and N-ch MOSFET switches.
4	VIN	power_in	Power supply input (2.3V to 5.5V) that must be closely decoupled to GND with a 10µF or greater ceramic capacitor.
5	VOUT	input	Output voltage feedback pin, where an internal resistive divider scales the output voltage for comparison to the internal reference voltage.
