LM2662M from Texas Instruments, in a SOIC-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 | FC | input | Frequency control for internal oscillator; FC open sets fOSC = 20 kHz (typ), FC connected to V+ sets fOSC = 150 kHz (typ). |
| 2 | CAP+ | passive | Connect to the positive terminal of charge-pump capacitor C1. |
| 3 | GND | power_in | Power supply ground input. |
| 4 | CAP− | passive | Connect to the negative terminal of charge-pump capacitor C1. |
| 5 | OUT | power_out | Negative voltage output providing inverted supply voltage with output current up to 200 mA and typical output resistance of 3.5 Ω. |
| 6 | LV | input | Low-voltage operation input; tie to GND when input voltage is less than 3.5 V; can be connected to GND or left open when input voltage is above 3.5 V. |
| 7 | OSC | input | Oscillator control input internally connected to 15-pF capacitor; accepts external capacitor to adjust oscillator frequency or external clock up to 150 kHz in inverter mode. |
| 8 | V+ | power_in | Power supply positive voltage input; operating range from 1.5 V to 5.5 V in inverter mode. |
