LM2623MMX

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

LM2623MMX 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 PGND power_in Power Ground
2 EN input Digital Active-Low Shutdown Input
3 FREQ input Analog Frequency Adjust. An external resistor connected between this pin and a voltage source sets the switching frequency of the LM2623.
4 FB input Analog Output Voltage Feedback
5 SGND power_in Signal Ground
6 VDD power_in Power Supply for Internal Circuitry
7 BOOT output Analog Bootstrap Supply for the Gate Drive of Internal MOSFET Power Switch
8 SW output Analog Drain of the Internal MOSFET Power Switch
