LM2663M from Texas Instruments, in a SOIC-8. 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 | SD | input | Shutdown control pin for LM2663; tie to GND for normal operation or apply voltage ≥2 V for shutdown mode. |
| 2 | CAP+ | passive | Connect to positive plate of external charge-pump capacitor C1. |
| 3 | GND | power_in | Power supply ground (0 V reference); serves as input voltage source in doubler mode (2.5 to 5.5 V). |
| 4 | CAP− | passive | Connect to negative plate of external charge-pump capacitor C1. |
| 5 | OUT | power_out | Negative voltage output (−V+) in inverter mode; must be tied to GND in doubler mode. |
| 6 | LV | input | Low-voltage mode control; tie to GND for V+ < 3.5 V, or tie to OUT in doubler mode; must be grounded when driving OSC with external clock. |
| 7 | OSC | input | Oscillator frequency control input; connect external capacitor to adjust frequency or external clock (max 150 kHz in inverter mode only; cannot be clock-driven in doubler mode). |
| 8 | V+ | power_in | Positive power supply input (1.5 to 5.5 V range) in inverter mode; positive voltage output (doubler function) in doubler mode. |
