HX7662-P from ZHHXDZ, in a DIP-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 | TEST | passive | Test pin that is not connected in normal use; tying it to V+ disconnects the internal oscillator from the OSC pin so the pump runs at a faster rate. |
| 2 | CAP+ | passive | Positive terminal of the pump capacitor C1, which must be connected to this pin. |
| 3 | GROUND | power_in | Ground reference pin; it is also the cascade connection point (pin 8 of a stage ties to pin 3 of the previous stage) and the split-supply midpoint. |
| 4 | CAP- | passive | Other (negative) terminal of the pump capacitor C1, switched between V+ and GND by the internal MOS switches. |
| 5 | VOUT | power_out | Negative output, Vout = -n x V+; output source resistance is about 60 ohm at +15V supply, and Vout should not be shorted to V+ for extended periods. |
| 6 | LV | input | Low-voltage pin that should be connected to GND for supplies below 8V to improve efficiency, and left open for higher supply voltages. |
| 7 | OSC | input | Oscillator pin left open for the nominal 10kHz oscillator; an external capacitor to V+ lowers the frequency, and an external clock may be applied through a 1k ohm series resistor. |
| 8 | V+ | power_in | Positive supply input rated for +4.5V to +20V, with an absolute maximum of -0.3V to +22V to GND. |
