Power Management Integrated Circuits or PMIC have been developed to efficiently manage the power supply and thermal control of complex electronic systems, such as computers and mobile phones. The EMC1704-2-AP-TR is a specific PMIC designed to improve thermal management. The purpose of this article is to explain the application field and working principle of the EMC1704-2-AP-TR.

Application Field

The EMC1704-2-AP-TR is a two-phase PMIC with adjustable outputs that enables direct thermal control of a Power System. It can be used in computers, servers, and mobile devices, as well as in a range of other applications that require high efficiency, precision thermal management. The two-phase configuration of the PMIC optimizes the power and temperature accuracy and maximizes flexibility for controlling the thermal system. The PMIC also offers fault protection and performance monitoring features to ensure system safety and reliability.

Working Principle

The EMC1704-2-AP-TR uses a constant-on-time (COT) current-mode control for both voltage regulation and thermal regulation. This approach provides the flexibility to accurately adjust the system voltage and temperature to meet the needs of the application. The COT current-mode control also regulates the operation of the two power phases independently. This allows the PMIC to be used in applications with multiple power rails, providing additional flexibility and control.

The EMC1704-2-AP-TR also uses an on-die temperature sensor to accurately monitor system temperature. This sensor is used to compare actual system temperature to a target temperature, which is set by the user. When the actual system temperature is lower than the target temperature, the PMIC will increase the voltage and current delivered to the system. This helps the system reach the desired target temperature faster. Conversely, if the actual system temperature is higher than the target temperature, the PMIC will reduce the voltage and current delivered to the system to dissipate the heat efficiently and quickly.

The EMC1704-2-AP-TR also offers a range of fault protection features to help ensure system safety and reliability. These features include over-temperature protection, over-voltage protection, and under-voltage protection. The PMIC also supports remote sensing, which enables the detection of faults in remote systems and can be used to prevent system shutdown due to external faults.

Conclusion

The EMC1704-2-AP-TR is a two-phase PMIC designed for high-performance and efficient thermal management in a range of applications. Its constant-on-time current-mode control provides the flexibility to adjust the system voltage and temperature to the needs of the application. Its on-die temperature sensor further enhances its ability to accurately monitor system temperature and quickly reach the desired target temperature. Finally, its range of fault protection features ensure system safety and reliability.
