LM25007MMX from Texas Instruments, in a VSSOP-8-0.65mm. 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 | SW | passive | Power switching node that connects to the inductor, bootstrap capacitor, and free-wheeling diode. |
| 2 | BST | passive | Bootstrap capacitor pin; an external capacitor (0.01µF ceramic recommended) is required between BST and SW. |
| 3 | RCL | passive | Current limit off-time programming pin; a resistor between this pin and RTN sets the off-time, preset to 17 µs if FB = 0V. |
| 4 | RTN | power_in | Circuit ground. |
| 5 | FB | input | Feedback signal from regulated output, connected to the inverting input of the internal regulation comparator with a 2.5V regulation threshold. |
| 6 | RON/SD | input | On-time set pin; a resistor between this pin and VIN sets the switch on-time (minimum recommended on-time 300ns at maximum input voltage), and pulling it below 0.7V shuts down the regulator. |
| 7 | VCC | power_out | Output of the internal high voltage 7V bias regulator that provides gate drive power; an external voltage above 7V shuts the internal regulator down, do not exceed 14V, and a 0.1µF local decoupling capacitor is recommended. |
| 8 | VIN | power_in | Input supply voltage with a recommended operating range of 9V to 42V. |
