HX7662-S

ZHHXDZ · Charge Pumps · SOP-8

HX7662-S from ZHHXDZ, in a SOP-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 input Test pin for oscillator frequency control; not connected in normal operation. Connecting to V+ increases oscillator frequency by enabling parasitic capacitance oscillation.
2 CAP+ passive Positive terminal of pump capacitor C1; connect external 10μF electrolytic capacitor with positive terminal to this pin and negative terminal to ground.
3 GND power_in System ground reference and negative supply return; connect positive terminal of reservoir capacitor C2 to this pin; serves as midpoint reference in voltage splitting applications.
4 VOUT output Negative output voltage from -4.5V to -20V; supplies inverted voltage to load; connect negative terminal of reservoir capacitor C2 here.
5 LV input Low voltage mode control input; connect to ground when supply voltage is less than 8V for improved conversion efficiency; leave open for supply voltages 8V and above.
6 OSC input Oscillator frequency control input; connect external capacitor between this pin and V+ to reduce operating frequency for lower load currents; leave open for nominal 10kHz oscillation.
7 V+ power_in Positive supply voltage input; accepts +4.5V to +20V; primary power source for charge pump operation.
8 CAP- passive Pump capacitor or cascade connection point; used for tying to Pin 3 of previous stage in cascaded configurations; internal charge pump network node.
