LM5085MYX from Texas Instruments, in a MSOP-8-EP. 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 | ADJ | input | Current limit threshold set by external resistor from VIN to ADJ in conjunction with external sense resistor or PFET's RDS(ON). |
| 2 | RT | input | External resistor from VIN to RT sets buck switch on-time and switching frequency; grounding this pin shuts down the controller. |
| 3 | FB | input | Voltage feedback to regulation and over-voltage comparators with 1.25V regulation threshold. |
| 4 | GND | power_in | Ground reference for all internal circuitry. |
| 5 | ISEN | input | Current sense input connected to PFET drain for RDS(ON) sense or to PFET source and sense resistor for external current sense. |
| 6 | PGATE | output | Gate driver output connected to external PFET gate. |
| 7 | VCC | power_out | Negative voltage regulator output relative to VIN that biases PFET gate driver; requires low ESR capacitor from VIN to VCC located close to pins. |
| 8 | VIN | power_in | Input supply voltage with operating range 4.5V to 75V; requires low ESR bypass capacitor located close to VIN and GND pins. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
