The TEA1998 is a new generation Power Supply Controller, Monitor, and Regulator from NXP. It is designed to provide a highly reliable and efficient power supply solution for a wide range of applications including industrial, automotive, computing, and communications systems. The TEA1998 is a single, low power, and high frequency DC-DC switching regulator, with adjustable output voltage and current. It is designed to minimize the system cost and board space while providing excellent power management.

The TEA1998 is based on NXP’s advanced and reliable TPS5420X series of switching regulators, which feature soft start and over-voltage protection functions. This device integrates a high-frequency PFM controller with both low-side and high-side MOSFET drivers. The TEA1998 also features a current-mode control loop, with an adaptive current limit function. The adaptive current limit is adjusted to as low as 5mA in order to minimize power consumption. The on-board driver is capable of operating at frequencies up to 500 kHz, enabling the power supply design to be optimized for high efficiency.

In addition to the on-board driver, the TEA1998 also incorporates an external MOSFET, allowing for the optimum thermal design for any given application. This device also allows for the use of both synchronous and low-side rectifiers. The low-side rectifier reduces the voltage drop across the MOSFET, resulting in improved efficiency and system power dissipation. The device also supports a variety of input voltage sources ranging from 4.5V to 40V.

The TEA1998 has an efficient built-in power supply controller, which is designed to protect the system against various faults. It provides comprehensive protection against over current, short circuits, and thermal over-temperature conditions. It also provides an adjustable fault recovery time so that the system can be reset or shutdown safely in case of fault conditions. The TEA1998 also supports a range of diagnostic functions.

The TEA1998 is compliant with multiple standards, including Automotive Electronics Council (AEC) and EMC/EMI standards. This makes it suitable for automotive applications, especially those requiring robust power management and fault protection. The device also supports a wide range of programming and diagnostic tools, enabling designers to customize the power system for specific applications.

In summary, the TEA1998 is a high-efficiency, low-power and configurable Power Supply Controller, Monitor, and Regulator from NXP. It features an efficient power supply controller and a range of configurable protective features. It also supports multiple input voltage sources and a variety of programming and diagnostic tools, making it ideal for systems requiring robust power management and fault protection. The TEA1998 is a highly reliable and efficient solution for a wide range of applications, including industrial, automotive, computing, and communications systems.
