MAX660ESA+ from Analog Devices Inc Maxim Integrated, 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 input: open selects 10kHz typ oscillator and tying to V+ selects 80kHz typ (40kHz min), with no effect when OSC is driven externally. |
| 2 | CAP+ | passive | Positive terminal of the charge-pump capacitor C1; the signal at CAP+ and CAP- runs at one-half the oscillator frequency. |
| 3 | GND | power_in | Power-supply ground input; the absolute maximum supply rating is V+ to GND = +6V. |
| 4 | CAP- | passive | Negative terminal of the charge-pump capacitor C1. |
| 5 | OUT | power_out | Negative voltage output in inverter mode (positive doubled output in doubler mode), rated for 100mA; it may be shorted to GND for 1sec but must not be shorted to V+, and continuous output current is limited to 120mA absolute maximum. |
| 6 | LV | input | Low-voltage operation input: tie to GND when input is below 3V, may be GND or open above 3V in inverter mode, must be tied to GND when overdriving OSC, and must be tied to OUT in doubler mode. |
| 7 | OSC | input | Oscillator control input with an internal 15pF capacitor; an external capacitor slows the oscillator and an external clock may overdrive it within 100mV of V+ and GND in inverter mode, but it must not be overdriven in doubler mode. |
| 8 | V+ | power_in | Positive power-supply input, specified at 1.5V to 5.5V operating supply voltage, with an absolute maximum of +6V to GND. |
