LM3485Q1MM

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

LM3485Q1MM 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 ISENSE input Current sense input that should be connected to the drain node of the external PFET; ISENSE voltage is rated −1.0 V to 36 V (absolute maximum).
2 GND power_in Signal ground for the controller.
3 NC unconnected No connection.
4 FB input Feedback input; connect to a resistor voltage divider between the output and GND for an adjustable output voltage, with FB voltage rated −0.3 V to 5 V (absolute maximum).
5 ADJ input Current limit threshold adjustment pin tied to an internal 5.5-µA current source; a resistor from this pin to the input supply sets the threshold, and ADJ voltage is rated −0.3 V to 36 V (absolute maximum).
6 PWR GND power_in Power ground for the external PFET gate driver.
7 PGATE output Gate drive output for the external PFET, swinging between VIN and VIN-5 V, with PGATE voltage rated −0.3 V to 36 V (absolute maximum).
8 VIN power_in Power supply input pin; recommended supply voltage is 4.5 V to 35 V.
