Furthermore, the LT3420EMS#TRPBF also offers a wide range of features and functions such as an on/off control, thermal protection, memory write protection, and many more. The LT3420EMS#TRPBF is designed to support applications requiring high power and precision, such as a cell site base station, industrial automation, medical, telecom, and other specialty applications.

Application Field

The LT3420EMS#TRPBF can be used in a wide variety of applications. For example, it can be used in industrial automation, medical, telecom, cell site base stations, and more. It is capable of powering a variety of power-hungry applications, such as portable electronic devices, computers, and servers. Additionally, it can be used for low-power applications, such as battery-powered devices.

In addition to its versatility, the LT3420EMS#TRPBF is also extremely reliable. It is designed to be able to operate in environments up to 85°C ambient temperatures and 100% humidity. Furthermore, it is tolerant to a wide range of temperature fluctuations and shock and vibration, making it an ideal solution for industrial applications.

Working Principle

The LT3420EMS#TRPBF’s working principle is based on the concept of ‘converting two input voltages to voltage and current rails’. The two input voltages, Nom/S and VDD, are converted to voltage and current rails using Charge Pump Voltage Converters (CPVC-1 and CPVC-2), two loop controllers (LC-1 and LC-2) and a power management unit (PMU).

The CPVC-1 converts the Nom/S input voltage to an output voltage of between 1.0V and 28V. Similarly, the CPVC-2 converts the VDD input voltage to an output voltage of between 1.0V and 28V. To regulate these output voltages, a pair of loop controllers is used to regulate the output voltage and current. The LC-1 regulates the output of the CPVC-1, while the LC-2 regulates the output of the CPVC-2.

The PMU contains all the necessary control signals that allow the LT3420EMS#TRPBF to start up, shut down and monitor the voltages. It also contains an integrated power supply fault monitor for monitoring faults on either input voltage. Finally, the PMU can be used to select between two input voltage sources, allowing the user to switch from Nom/S to VDD if needed.

Conclusion

The LT3420EMS#TRPBF is an advanced power management module for the digital power domain. It has a wide range of features and is capable of powering a variety of power-hungry applications. It is designed to be reliable and can operate in a wide range of environments. Furthermore, its working principle is based on the concept of ‘converting two input voltages to voltage and current rails’. The LT3420EMS#TRPBF is an ideal solution for applications requiring high power and precision.
