It is often used in a variety of applications where precision power distribution and driving of digital circuits are important. This article will discuss the field of application and working principle of TPS22964CYZPT.

Field of Application

TPS22964CYZPT is an integrated power management integrated circuit (PMIC) designed for high speed and low voltage applications. It is suitable for 12V and 48V applications, such as motherboard, industrial equipment and medical devices. The device can be used in both synchronous and asynchronous systems, providing precise power distribution and load driving. In addition to providing precise and clean power to critical components, it also offers optimized circuit topologies for mitigating noise and efficient power management.

The TPS22964CYZPT includes four 4-channel low-on resistance P-Channel MOSFETs and four 3-channel low-on resistance N-Channel MOSFETs. The device comes in a .4mm thin quad flat no-lead (QFN) package, which makes it suitable for high density applications with limited space. In addition to being configurable as a single stage, multiple stages, and as a combination of both, the device can also be configured for dual and triple output converters. The device also has a built-in overvoltage protection, overcurrent protection, power-fail detection and adjustable switching frequency.

Working Principle

The TPS22964CYZPT uses four 4-channel low-on resistance P-Channel MOSFETs to provide precision power distribution and load driving with minimal circuit complexity. The device has a built-in regulator with a regulated output voltage of up to 12V, making it suitable for low voltage applications. The device uses internal power-on reset and adjustable operating frequency, to ensure proper power management. The device also features adjustable soft start and overvoltage protection to ensure the safety of the critical components.

When the TPS22964CYZPT is powered on, the internal regulator sets the voltage in the output stage to the desired voltage. When the load is connected to the output stage, the voltage regulator maintains the set voltage by monitoring the output current. If the load increases, the voltage regulator adjusts the output voltage to maintain the set point. The device then monitors the output voltage and limits the output current to the set point by adjusting the voltage. This process continues until the load is removed.

In addition to providing stable, low-noise power distribution and low-loss load driving with minimal circuit complexity, the TPS22964CYZPT is also capable of providing precise overvoltage protection. The device uses built-in adjustable overvoltage protection to ensure that the input voltage does not rise above the predetermined level. This prevents any damage to the critical components, due to excessive voltage.

Conclusion

TPS22964CYZPT is a highly integrated power management integrated circuit (PMIC) designed to provide stable, low-noise power distribution and low-loss load driving with minimal circuit complexity. It is suitable for 12V and 48V applications and is often used in precision applications where power distribution and driving of digital circuits are required. The device comes with a built-in regulator, overvoltage protection, overcurrent protection, power-fail detection and adjustable switching frequency, making it an ideal choice for precision power distribution and load driving applications.
