MAX660MX 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 | FC | input | Frequency control logic input; select 10 kHz (open) or 80 kHz (tied to V+) oscillator frequency; no effect when OSC is externally driven. |
| 2 | CAP+ | passive | Positive terminal connection for external charge-pump capacitor; use low-ESR capacitor to minimize output impedance and maximize conversion efficiency. |
| 3 | GND | power_in | Ground reference in voltage inverter mode or positive voltage supply input in voltage doubler mode; bypass with low-ESR capacitor placed close to device. |
| 4 | CAP- | passive | Negative terminal connection for external charge-pump capacitor; use low-ESR capacitor to minimize output impedance and maximize conversion efficiency. |
| 5 | OUT | power_out | Negative voltage output in inverter mode (100 mA maximum continuous output current, 6.5 Ω typical output impedance) or positive supply return in doubler mode. |
| 6 | LV | input | Low-voltage mode control input; tie to GND when input voltage is below 3.5 V or when OSC is externally driven; tie to OUT in doubler mode. |
| 7 | OSC | input | Oscillator frequency control input with internal 15-pF capacitor; external capacitor slows oscillator or external clock up to 150 kHz can drive oscillator in inverter mode only. |
| 8 | V+ | power_in | Power supply positive voltage input at 1.5-5.5 V (inverter LV = GND), 3.5-5.5 V (inverter LV = open), or 2.5-5.5 V (doubler mode); functions as positive voltage output in doubler mode. |
