LM25085QMYX from Texas Instruments, in a MSOP-8-EP. 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 adjust: the current limit threshold is set by an external resistor from VIN to ADJ, together with the external sense resistor or the PFET RDS(ON). |
| 2 | RT | input | On-time control and shutdown: an external resistor from VIN to RT sets the buck switch on-time and switching frequency, and grounding this pin shuts down the controller. |
| 3 | FB | input | Voltage feedback from the regulated output, input to the regulation and over-voltage comparators, with a regulation level of 1.25 V. |
| 4 | GND | power_in | Circuit ground, the ground reference for all internal circuitry. |
| 5 | ISEN | input | Current sense input for current limit detection, connected to the PFET drain for RDS(ON) sensing or to the PFET source and sense resistor when using a sense resistor. |
| 6 | PGATE | output | Gate driver output that connects to the gate of the external PFET. |
| 7 | VCC | power_out | Output of the gate driver bias regulator (negative relative to VIN) that biases the PFET gate driver; a low ESR capacitor is required from VIN to VCC, located as close as possible to the pins. |
| 8 | VIN | power_in | Input supply voltage with an operating range of 4.5 V to 42 V; a low ESR bypass capacitor must be located as close as possible to the VIN and GND pins. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
