Power Management Integrated Circuits (PMICs) are re-emerging as invaluable components in the modern electronics industry. Moore\'s Law has enabled tighter integration of system-on-chip concepts, which require ever-more powerful PMICs to keep up. The family of such voltage regulator products is called the BD9885FV-E2 and it plays a vital role in a variety of different applications.This PMIC consists of a high-efficiency DC-DC converter with integrated synchronous driver that can supply up to 4 A output current over a wide input voltage range between 1.8 V and 5.5 V. The BD9885FV-E2 simplifies board layout and reduces the bill of materials (BOM) by reducing the total external components needed to provide the necessary power resources. It is designed to help achieve high efficiency and extend battery life in portables powered by Li-ion batteries.The BD9885FV-E2 application field includes laptop and tablet computers, remote-sensing systems, cellular terminals, and power management in motorized equipment. The device is also suitable for any embedded application that requires a compact form factor yet requires both high power efficiency and extremely low power consumption. It is fully compliant with the PMIC standards defined by the European Commission (EC) and is certified for use in the EU region.The BD9885FV-E2 can be used with a variety of process technologies, including Traditional CMOS, Silicon-On-Insulator (SOI), and SiGe-on-insulator (SGOI). SOI and SGOI are especially well-suited for high-performance embedded devices requiring low on-chip power dissipation. This flexibility places the BD9885FV-E2 in a class of its own, and it is being used in the most demanding applications requiring the highest levels of power efficiency and reliability.The BD9885FV-E2 working principle involves the use of a buck converter based on a Field-Effect Transistor (FET). A Buck-Mode FET is used in the BD9885FV-E2 to provide an efficient and cost-effective way to convert input voltages into multiple output voltages at the desired current levels. The device also includes on-chip compensation circuitry that ensures it\'s operating characteristics are optimized for switching frequencies over the intended operating temperature range and load conditions.It is also possible to synchronize the BD9885FV-E2 to an external clock signal that can be used to control the switching frequency and optimize efficiency or reduce EMI emissions. This makes the BD9885FV-E2 suitable for high-performance applications that demand speed and reliability.In addition to its efficient power management, the BD9885FV-E2 also offers several features such as protection against overcurrent, under voltage, and over voltage conditions. It also supports dynamic voltage scaling to dynamically adjust the output voltage to meet changing load conditions. The device also integrates a wide range of housekeeping functions needed for reliable operation, such as reset and enable functions, as well as an enable function for power sequencing.Overall, the BD9885FV-E2 is a highly integrated, compact and cost efficient solution that meets the requirements of the most demanding applications. Its flexibility and range of features make it an ideal choice for a wide range of power systems. Its efficient power management, wide range of protection features, and housekeeping functions ensure reliable system performance with minimal board size and low external component count. The device is also compliant with the latest PMIC standards and is certified for use in the EU region.
