ICL7660N

HGSEMI · DC-DC Converters · DIP-8

ICL7660N from HGSEMI, 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 N.C unconnected No internal connection (listed as 空, empty), so this pin is left unconnected.
2 CAP+ passive Positive terminal of the external energy-storage (pump) capacitor, which the datasheet says requires three small 10 µF external capacitors in total.
3 GND power_in Power ground pin, the reference for V+ and the other pins (V+ to GND maximum rating is 9 V).
4 CAP- passive Negative terminal of the external energy-storage (pump) capacitor, which switches between GND and VOUT during operation.
5 VOUT output Negative voltage output that is the inverse of V+ (for example, VOUT = -5 V when V+ = 5 V); the GND to VOUT maximum rating is 9 V.
6 LV input Low-voltage control pin that must be tied to GND when V+ is 3.5 V or below and left open when V+ is above 3.5 V; its input voltage is limited to -0.3 V to V+ +0.3 V and its input current to 20 µA.
7 OSC passive Oscillator pin whose external capacitor COSC sets the switching frequency; its input voltage is limited to -0.3 V to V+ +0.3 V.
8 V+ power_in Positive supply input, specified for 1.5 V to 9 V with an absolute maximum of 9 V to GND.
