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. |

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)
