LM2623AMMX from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PGND | power_in | Power ground connection for output stage; reference potential for output power dissipation path |
| 2 | EN | input | Digital active-low shutdown control input; device operates in normal mode above 0.7 VDD and enters shutdown below 0.15 VDD |
| 3 | FREQ | input | Frequency adjust input pin; external resistor connected between this pin and voltage source sets switching frequency from 300 kHz to 2 MHz |
| 4 | FB | input | Output voltage feedback input; feedback threshold is 1.24 V nominal, ranging from 1.2028 V to 1.2772 V over -40 °C to 85 °C temperature range |
| 5 | SGND | power_in | Signal ground reference potential for internal control and feedback circuitry |
| 6 | VDD | power_in | Power supply input for internal circuitry; operating voltage range 3 V to 5 V per recommended operating conditions |
| 7 | BOOT | power_out | Bootstrap supply output for the internal gate drive of the MOSFET power switch |
| 8 | SW | output | Drain of internal MOSFET power switch; switching node that connects to external inductor and Schottky diode in boost topology |
