SRK2001TR from STMicroelectronics, in a SSOP-10-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Device supply voltage, operating range 4.5-32 V (turn-on ~4.5 V, turn-off ~4.25 V). Internally clamped by a 36 V Zener (ICCZ_max = 25 mA). Requires a bypass capacitor to GND placed as close as possible to the pin to buffer pulsed gate-drive currents. |
| 2 | GND | power_in | Return for device bias current and gate-drive currents. Must be routed to the common point where the source terminals of both synchronous rectifier MOSFETs are tied. Also acts as the thermal pad reference (soldered to ≥25 mm² copper for thermal dissipation). |
| 3 | GD1 | output | Gate driver output for synchronous rectifier section 1. Totem-pole output capable of high peak currents (source ~0.35 A, sink up to 4 A during ZCD turn-off). Output high level clamped to ~11 V (VGDclamp 9-13 V) to protect standard-level MOSFETs. Connect directly to the SR1 MOSFET gate. |
| 4 | SVS1 | input | Source voltage sensing (Kelvin) for section 1. Provides the reference for the DVS1 drain sense. Absolute rating -3 to 3 V referred to GND. Connect directly to the source terminal of SR1 MOSFET. |
| 5 | DVS1 | input | Drain voltage sensing for section 1 (high-voltage Kelvin sense, up to 90 V referred to SVS1). Connect to the SR1 MOSFET drain through a series resistor of at least 100 Ω to limit current into the internal HV clamp/switch. |
| 6 | DVS2 | input | Drain voltage sensing for section 2 (high-voltage Kelvin sense, up to 90 V referred to SVS2). Connect to the SR2 MOSFET drain through a series resistor of at least 100 Ω. |
| 7 | SVS2 | input | Source voltage sensing (Kelvin) for section 2. Reference for the DVS2 drain sense. Absolute rating -3 to 3 V referred to GND. Connect directly to the source terminal of SR2 MOSFET. |
| 8 | GD2 | output | Gate driver output for synchronous rectifier section 2. Totem-pole output, high level clamped to ~11 V. Connect directly to the SR2 MOSFET gate. |
| 9 | PROG | input | Programming pin for sleep/burst-mode entry-exit conduction duty cycles. An internal precise current source (~10 µA at startup) develops VPROG across a resistor to GND; the level selects one of several predefined duty-cycle sets from internal lookup tables. Absolute rating -0.3 to 3.3 V. |
| 10 | EN | input | Enable / remote ON-OFF with internal pull-up current source (IEN_run ~6 µA). During run mode, pulling below VEN_OFF (~0.3 V) stops operation and enters low-consumption; releasing above VEN_ON (~0.62 V) resumes. During startup the pin voltage set by REN selects the automatic sleep-mode duty cycle (or disables sleep mode entirely if held above VSM_off). Absolute rating -0.3 to 3.3 V. |
