SRK2001A

STMicroelectronics · AC-DC Controllers And Regulators · SOP-10

SRK2001A from STMicroelectronics, in a SOP-10. 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 VCC power_in Supply voltage of the device; operating range 4.5 V to 32 V internally clamped to 36 V; bypass capacitor to GND located as close as possible provides clean supply for control circuitry and energy buffer for pulsed gate drive currents.
2 GND power_in Return of device bias current and return of gate drive currents; route to common point where source terminals of both synchronous rectifier MOSFETs are connected.
3 GD1 output Gate driver output for section 1 with totem pole output stage capable of driving power MOSFETs at high peak current levels; high-level voltage clamped to about 11 V to avoid excessive gate voltages; connect directly to SR MOSFET gate terminal.
4 SVS1 input Source voltage sensing for section 1 serving as reference voltage for corresponding drain sensing signal DVS1; connect directly to respective source terminal of corresponding synchronous rectifier MOSFET.
5 DVS1 input Drain voltage sensing for section 1; connect to respective drain terminal of corresponding synchronous rectifier MOSFET using series resistor of 100 Ω.
6 DVS2 input Drain voltage sensing for section 2; connect to respective drain terminal of corresponding synchronous rectifier MOSFET using series resistor of 100 Ω.
7 SVS2 input Source voltage sensing for section 2 serving as reference voltage for corresponding drain sensing signal DVS2; connect directly to respective source terminal of corresponding synchronous rectifier MOSFET.
8 GD2 output Gate driver output for section 2 with totem pole output stage capable of driving power MOSFETs at high peak current levels; high-level voltage clamped to about 11 V to avoid excessive gate voltages; connect directly to SR MOSFET gate terminal.
9 PROG input Programming pin for burst-mode exiting conduction duty-cycle; resistor from pin to GND supplied by internal current source sets voltage VPROG determining exit duty-cycle from internal lookup table; proper resistor value determines operation parameters.
10 EN input Enable pin with internal pull-up for remote ON/OFF control; when pin voltage below VEN_OFF threshold during run mode controller stops operating and enters low consumption state; operation resumes when pin voltage exceeds VEN_ON threshold.

CAD (KiCad official)

  • Symbol: SRK2001A
  • Footprint: Package_SO:SOIC-10_3.9x4.9mm_P1mm
  • 3D model: SOP-10, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: srk2001a-etched.step / srk2001a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); srk2001a.step / srk2001a.glb are the bare package body.
