The IR3812MTRPBF is a DC/DC switching regulator designed to deliver consistent power output, cost-effectively, in a wide variety of applications. As a member of Infineon Technologies’ Multi-output Power Management family, it offers two output step-down voltage settings, adjustable from 0.8V to 4.3V, and can provide output power up to 8A. It is ideal for regulating power in consumer/industrial applications including consumer devices, computer peripherals, portable equipment, portable medical devices, digital streaming media devices, automotive infotainment systems, network and telecom applications and LED lighting systems.The IR3812MTRPBF\'s working principle is based on constant frequency, current mode control, which can provide precise output voltage regulation, current limiting and soft start protection, and reduce the system\'s external components. Its high-frequency, light load modulation scheme keeps the output current and temperature constant while operating at heavy and light load conditions. The power stage consists of a high frequency MOSFET, a small number of passive components, inductor and output capacitor, which enables small form factor, low cost and high efficiency. High frequency switching also reduces EMI by reducing the switching ripple. With the integrated DSP and comparator, the IR3812MTRPBF can provide precise feedback to the microcontroller and is suitable for controlling the application\'s voltage, temperature, current and other parameters.The IR3812MTRPBF is well suited for applications that require stable output currents and dynamic load response. Its input voltage range can range from 9V to 39V, making it suitable for a wide range of industrial, telecom and automotive applications. Its external frequency synchronization is capable of supporting frequencies up to 1MHz, enabling a wide range of frequency adjustment to achieve optimal efficiency and thermal performance in the system. Its multiple safety features also include over temperature, under voltage and over current protections to ensure system reliability. The IR3812MTRPBF can be easily configured and optimized with its advanced features, allowing its output voltage, switching frequency, current limit, slope compensation and total output power to be adjusted according to the application\'s requirements. It is also designed with intelligent power saving technology to reduce power consumption. With the advanced integrated power management and dynamic power management features, its operational efficiency can reach up to 96%. It can also provide a vast range of optional features, including active PFC, phase spread, standby mode, phase skip and crossover mode. The IR3812MTRPBF’s compact design and significant performance characteristics make it an ideal DC/DC switching regulator for space-constrained industrial, consumer, mil/aero and other applications. In addition, its small conductive footprint and industry-standard power pins make it highly compatible with existing power systems designs, making it an easy and reliable choice for designers to meet their power management needs.
