LM25085MM 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 | ADJ | input | Current limit threshold adjustment input set by external resistor from VIN used in conjunction with sense resistor or PFET RDS(ON). |
| 2 | RT | input | On-time control and shutdown input; external resistor from VIN sets buck switch on-time and switching frequency, grounding disables controller. |
| 3 | FB | input | Voltage feedback input from regulated output for regulation and over-voltage comparators with 1.25V regulation threshold. |
| 4 | GND | power_in | Circuit ground providing reference for all internal circuitry. |
| 5 | ISEN | input | Current sense input for current limit detection; connect to PFET drain for RDS(ON) sensing or to PFET source with sense resistor for alternative sensing. |
| 6 | PGATE | output | Gate driver output signal connected to external PFET gate. |
| 7 | VCC | power_out | Gate driver bias regulator output providing voltage relative to VIN for PFET gate driver biasing; requires low ESR capacitor from VIN to VCC. |
| 8 | VIN | power_in | Input power supply voltage with operating range of 4.5V to 42V; requires low ESR bypass capacitor located close to VIN and GND pins. |
