TPS62822DLCT - DC DC Switching Regulators

The TPS62822DLCT is a highly integrated, low quiescent current synchronous step-down dc-dc regulator that uses a single inductor to generate a regulated output current. It is designed to operate with a switching frequency of up to 1.2 MHz and provides an output current up to 2 A. The TPS62822DLCT is ideal for powering high power, portable applications such as tablets and handsets.

Application field

The TPS62822DLCT can be used in application areas such as:

• Wireless Base Stations
• High power digital video cameras
• Tablets and mobile handsets
• Ultra low power portable products
• Battery operated industrial system
• Automotive systems

These application areas benefit from the TPS62822DLCT’s high efficiency, low quiescent current, fast transient response, and wide input voltage range, which make it ideal for powering high power and portable applications. Furthermore, its precise output voltage accuracy allows for precise and reliable voltage regulation.

Working principle

The TPS62822DLCT is designed to operate with a constant 1.2MHz frequency and utilizes internally compensated advanced CMOS technology. It is a synchronous buck regulator, which means that current is supplied to the output using a single inductor, which stores and releases energy through the switching of the schematic components.When the device enters normal operation, the output voltage is regulated using an internal error amplifier and the switching frequency of the regulator is maintained. The error amplifier constantly compares the output voltage with a predetermined reference voltage and adjusts the duty cycle of the output voltage switch accordingly.The TPS62822DLCT also features a low-side switch. This low-side switch is responsible for switching the inductor current from the input voltage to the output voltage path, thus limiting the voltage spike on the output voltage.The TPS62822DLCT also includes over-temperature and over-current protection to further ensure safe and reliable operation.

Conclusion

In conclusion, the TPS62822DLCT is a highly integrated, low quiescent current synchronous step-down dc-dc regulator ideal for powering high power and portable applications. It is designed to operate with a constant 1.2MHz frequency and utilizes internally compensated advanced CMOS technology. It can be used in areas such as wireless base stations, digital video cameras, tablets and handsets, or automotive systems. Furthermore, its precise output voltage accuracy allows for precise and reliable voltage regulation, while protection features such as over-temperature and over-current protection ensure safe and reliable operation.
