This charger is also suitable for solar power systems and other renewable green energy applications.

Working Principle

The BQ24060DRCTG4 is a two-phase synchronous, constant-current/constant-voltage (CC/CV) step down DC/DC buck charger. A buck charger is a switch mode power supply (SMPS) that uses switches and capacitors to control the voltage and current coming into a system. It takes in high amperage power and outputs a precise voltage and current, making it perfect for a variety of demanding applications. The BQ24060DRCTG4 has an adjustable output voltage of up to 5.5V and with an output current of up to 4A, making it capable of charging Li-Ion and Li-Pol batteries. It employs a constant voltage regulation loop for AC adapter input voltage protection and provides a fast 10mV/4mV line/load regulation, respectively. The device also includes over-temperature protection and overload protection to ensure that batteries are not overcharged and are kept safe.

Conclusion

The BQ24060DRCTG4 is an extremely powerful and versatile battery charger. With its adjustable output voltage of up to 5.5V and maximum output current of 4A, it can handle a wide variety of applications. Its robust design and tight voltage and current regulation make it ideal for use in automotive, medical, industrial, and green energy applications. This device has established itself as a reliable and efficient battery charger, as well as an indispensable part of many systems.
