TPS62822DLCR Application Field and Working Principle

TPS62822DLCR is a single integrated-type DC-DC switching regulator, which belongs to PMIC (Power Module Interface Circuit) voltage regulator family. It is a planar-integrated DC/DC switching regulator, which is responsible for power supply to DC power grids. With low standby current, wide output range, fast transient response and excellent dynamic response, it is widely used in power systems with high power consumption or with limited power supply.In this article, we will discuss the application fields and working principle of TPS62822DLCR.

Application Fields

TPS62822DLCR is suitable for a wide range of DC power supply systems and can achieve high power compatibility in low power, low voltage and high voltage. Its main application fields include:

• Automobile and motorcycle power supplies;
• PC power supplies;
• Consumer electronic power supplies;
• Industrial power supplies;
• Medical and laboratory equipment power supplies;
• Data acquisition and monitoring equipments power supplies;
• Telecommunication power supplies;
• Portable instrument power supplies;
• High/low current, simple/complex power supplies;
• Aviation, military and other environmental equipment power supplies.

Working Principle

The working principle of TPS62822DLCR is quite simple. The main components of this type of DC/DC switching regulator are power semiconductor (MOSFET or IGBT switch, diode, and other active elements) and passive components. It uses an internal synchronous PWM regulator with automatic shutdown control, and its voltage range can be adjusted through external resistor.The input voltage of TPS62822DLCR is mainly applied to the upper switching MOSFET, while the lower switching MOSFET is generally connected to the ground. With the effective control of the internal high-speed PWM control, the upper/lower MOSFETs can be alternately turned off and on, which enables the upper MOSFET\'s full power to be output for the conversion of the output voltage. At the same time, the diode D2 is used to help the current gain (current loop) by taking the current of the inductor (L) to the output capacitor (Cout).The main advantages of TPS62822DLCR are its good voltage regulation accuracy and its high speed dynamic response. TPS62822DLCR can generate and maintain stable output voltage even if the input voltage changes, and its voltage output range is also wide.In addition, in order to ensure better efficiency and power stability in the whole output range, TPS62822DLCR has two mode ports (mosel) control pins. By setting their voltage level, the user can better adjust the device\'s power regulation environment.

Conclusion

In summary, TPS62822DLCR is a single integrated DC-DC switching regulator belonging to PMIC voltage regulator family. It has wide application field, wide output range and excellent dynamic response, which greatly facilitate the power supply design of DC circuits. In addition, its voltage regulation accuracy and speed of dynamic response are also great.
