SCT · DC-DC Converters · TSOT-23-6L
SCT2401TVBR from SCT, in a TSOT-23-6L. 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 | BST | passive | Power supply for the high-side power MOSFET gate driver; a 0.1uF or greater ceramic capacitor must be connected between BST and SW. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | FB | input | Buck converter output feedback sensing input; a resistor divider from VOUT to FB sets the output voltage, and the device regulates FB to the internal 0.81V reference typically. |
| 4 | EN | input | Enable logic input that accepts voltages up to VIN and can be tied to VIN directly; precision thresholds are 1.21V rising and 1.1V falling for programmable UVLO and hysteresis. |
| 5 | VIN | power_in | Power supply input with an operating range of 4.5V to 40V that must be locally bypassed. |
| 6 | SW | output | Switching node of the buck converter. |
