Working Principle of RTQ2522BGQW (2)

RTQ2522BGQW (2) is based on a linear voltage regulation topology. It provides two non-isolated, two-phase synchronous rectification DC-independent buck regulators, each with its own output voltage. Both regulators are controlled utilizing an integrated circuit (IC) called UCC28820BS. This IC includes both high- and low-side MOSFET drivers, a logic interface, a fast PWM comparator and a trimming reference voltage.The dual channel/output regulators are capable of supplying up to 28A of output current across the two channels. The RTQ2522BGQW (2) has separate input and output power connections that allow for maximum flexibility. The input voltage range of the module is from 4.5V to 17V and the output voltage range is from 0.6V to 5V.The module provides a comprehensive set of features such as adaptive On-Time (AOT) for high efficiency and output voltage accuracy, selectable frequency between 300kHz to 600kHz, as well as over-voltage/over-current protection. Additionally, this regulator module is halogen free, given enhanced environmental friendliness.

Conclusion

The RTQ2522BGQW (2) is an advanced, high performance linear voltage regulator module that is suitable for a wide range of applications due to its high power capability, flexibility, and overall efficiency. It provides two independent, synchronous rectification DC buck regulators with up to 28A output current and 0.6V-5V output voltage range. It is optimized for use in mobile computing platforms to minimize the system\'s total power dissipation in a very small form factor.
