LM25085MM

Texas Instruments · DC-DC Converters · VSSOP-8-0.65mm

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.
