LM3489MM

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

LM3489MM 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 The current sense input must be connected to the PFET drain terminal directly or through a series resistor up to 600 Ω for 28 V > VIN > 35 V (limit as printed in the datasheet).
2 GND power_in Signal ground for the controller.
3 EN input Enable pin: connect to ground to shut down the part or float to enable operation (internally pulled high and clamped at 8 V typical); recommended EN voltage is 5.5 V maximum, and it can also be used for a UVLO function.
4 FB input Feedback input; connect to a resistor voltage divider between the output and GND to set the adjustable output voltage.
5 ADJ input Current limit threshold adjustment pin tied to an internal 5.5 µA current source; a resistor between this pin and VIN sets the overcurrent threshold compared against the ISENSE voltage.
6 PGND power_in Power ground for the external PFET gate drive.
7 PGATE output Gate drive output for the external PFET, which swings between VIN and VIN minus 5 V.
8 VIN power_in Power supply input pin; recommended VIN supply range is 4.5 V to 35 V.
