Working Principle of ICL7660CSA+

The ICL7660CSA+ DC–DC switching regulator integrates a full-wave rectification, charge pump, and voltage regulator into a single-package. Its full-wave rectification ensures low-ripple and no-noise operation. The charge pump further reduces the ripple at the output. The voltage regulator prevents the output voltage from exceeding the rated voltage.

The ICL7660CSA+ DC–DC switching regulator works by charging and discharging an external capacitor connected to a change pump. During the charge phase, current flows through an inductor and a diode to the positive and negative output terminals, respectively. The inductor stores energy during this phase and the diode prevents reverse current flow. The discharge phase occurs after the inductor has been charged. During this phase, the diode closes, and the energy stored in the inductor is released back to the output terminals.

The device features high current output and low output noise, with a wide operating range. The integrated voltage regulator ensures minimal voltage overshoot, line regulation and load regulation for a stable output voltage.

Conclusion

In conclusion, the ICL7660CSA+ DC-DC switching regulator is a robust, efficient and versatile DC-DC switching regulator that provides high current output and low output noise over a wide operating range. It is suitable for a variety of applications, such as transducers, active filters, power sequence supplies, and computer peripherals. The integrated voltage regulator ensures minimal line and load regulation, making the device reliable and stable.
