Working principle of BQ2668-8R

The working principle of the BQ2668-8R is the use of a voltage step down switching voltage regulator. It is designed to accept an input voltage of 3.6V to 12V and provide a stable output voltage of 1.8V to 10V. The switch voltage regulator incorporates a step down transformer and an efficient switch mode power supply circuit. This transformer reduces the input voltage to the desired output voltage, then the output voltage is rectified by a pre-regulator diode and stored in an output capacitor. Finally, the switching regulator converts the low-voltage ripple output of the output capacitor to a stable supply voltage with low output ripple.

Thanks to its low quiescent current features, BQ2668-8R is an ideal choice for mobile applications that need both high power efficiency and longer battery life. Additionally, its small size makes it very easy to integrate into any mobile system.
