Switching at 10 kHz, it uses two external capacitors — no inductor — to produce the inverted output, making it a compact solution for generating a negative bias rail on a mixed-signal board. ## What the 10 kHz switching frequency means for your supply design The 10 kHz switching rate sets the output ripple frequency. With the recommended external capacitors, the ripple amplitude is low enough for op-amp or ADC negative rails, but the charge pump's output impedance increases with load current — budget the voltage drop at your load current from the datasheet's output resistance curve. Because the topology is a charge pump, not a buck-boost, the output is simply -Vin with no regulation. For a 12 V input, the output is -12 V minus the voltage drop across the internal switches and the flying capacitor ESR. ## SOIC-14 package and board integration The tube packaging means it ships in antistatic tubes, not tape-and-reel — factor this into your pick-and-place feeder setup if you are running high-volume assembly. Fully ROHS3 compliant, the part meets the latest EU restriction directive without exemptions.","metaTitle":"ICL7662CBD+ Analog Devices Charge Pump Inverter, 10kHz","metaDescription":"ICL7662CBD+ active-production charge pump inverter from Analog Devices. 4.5-20V input, -Vin output, 10kHz switching.
