SD6039A

SHOUDING · DC-DC Converters · SOP-8

SD6039A from SHOUDING, in a SOP-8. 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 N/C unconnected No connect pin, not connected internally; the datasheet gives no electrical limits for it.
2 VIN power_in Main supply pin for the 5V to 16V unregulated input, which must be closely decoupled to GND with a 20μF or greater ceramic capacitor to prevent large voltage spikes.
3 SW output Switch node connected to the inductor and to the drains of the internal main and synchronous power MOSFETs, and should be kept small in area because of high-frequency voltage swing.
4 GND power_in Ground pin; analog grounds should connect to a common node that ties to the power ground behind the output capacitors.
5 FB input Feedback pin that receives the voltage from an external resistive divider across the output, with VOUT = 0.8V • [1 + (R2/R3)].
6 COMP passive Output of the transconductance error amplifier and input to the current comparator, compensated by a series R-C connected to ground.
7 EN input ON/OFF control where forcing the pin above 1V enables the part and forcing it below 0.7V shuts it down; it must not be left floating.
8 N/C unconnected No connect pin, not connected internally; the datasheet gives no electrical limits for it.

CAD (KiCad official)

  • Symbol: SD6039A
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: sd6039a-etched.step / sd6039a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sd6039a.step / sd6039a.glb are the bare package body.
