STMicroelectronics has unveiled the STNRG012TR, a digital combo controller representing a significant advancement in power management technology. This innovative device incorporates a multimode power factor correction (PFC) controller, a high-voltage double-ended time shift controller for LLC resonant half-bridge, an 800 V start-up generator, and a sophisticated digital engine for comprehensive control and supervision.
The versatility of the STNRG012TR is evident in its ability to handle both AC and DC input voltages across a wide range. This capability makes it particularly well-suited for switch-mode power supply (SMPS) applications ranging from 90 W to 300 W. Examples of such applications include systems that need to seamlessly transition between mains AC power and battery power, such as emergency lighting solutions.
One of the standout features of the STNRG012TR is its implementation of a total harmonic distortion (THD) algorithm, which not only enhances power quality by reducing distortion but also ensures compliance with stringent energy efficiency regulations. The digital algorithms are executed by an 8-bit core equipped with dedicated fast peripherals. Moreover, essential parameters are stored in internal ROM, facilitating full programmability during the production phase. This level of configurability and flexibility enables designers to optimize performance according to specific application requirements.
Furthermore, the STNRG012TR supports external communication via a UART port, enabling functions such as monitoring, black box data storage, software patching, and testing. This capability enhances usability and facilitates debugging and optimization processes during development.
In summary, the STNRG012TR from STMicroelectronics empowers designers with a comprehensive solution for power management in SMPS applications. By integrating multiple functionalities into a single device, it reduces component count, complexity, and footprint while accelerating time to market and minimizing costs. Its combination of advanced features, flexibility, and efficiency makes it a compelling choice for next-generation power electronics applications.
