LP6493BSOF

LOWPOWER · AC-DC Controllers & Regulators · SOP-8

LP6493BSOF from LOWPOWER, in a SOP-8. 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 FB input Voltage feedback input with 0.6V reference, connected to the output divider (VOUT = 0.6V × (1 + RUP/RDN)) and also used for cable compensation.
2 CS input Output current sense pin; current limit trips when CS voltage exceeds 65mV (LP6493BSOF) per IOUT = VCS/RSEN.
3 GND power_in Ground.
4 VIN power_in Input supply voltage, 8V to 30V operating range (absolute maximum -0.3V to +36V).
5 SW output Switch node pin of the internal power MOSFETs (absolute maximum -0.3V to +36V), shorted with pin 6.
6 SW output Switch node pin of the internal power MOSFETs (absolute maximum -0.3V to +36V), shorted with pin 5.
7 GND power_in Power ground, shorted with pin 8.
8 GND power_in Power ground, shorted with pin 7.
