It also has over-current and over-voltage protection, as well as high-frequency oscillation and soft-start features to ensure safe and reliable operation. These features combined with an on-chip high-speed PWM controller and a high-accuracy voltage regulator enable the board to deliver an optimized solution for small size, high-efficiency, and high accuracy.

Application Field

The MAX20003ATPA/V+C2 is widely used in various applications such as industrial systems, consumer electronics, data centers, medical equipment, telecommunications, and automotive systems. It is designed to meet the demanding requirements of voltage regulator applications such as motor drives, battery charging systems, and other high-current applications. The board can also be used in applications with high-precision output voltages, such as automotive smart power controllers, where the accuracy and stability of the output voltage are crucial.

Furthermore, the MAX20003ATPA/V+C2 is specifically designed to meet the medical industry’s requirements, such as lowered output noise, higher-efficiency operation and ATEX compliance, enabling it to be used in medical systems. The board also features a built-in E-fuse, which enables safe and reliable operation with a minimum of external components.

Working Principle

The MAX20003ATPA/V+C2 works on a synchronous buck-boost topology, which allows it to effectively manage the input voltage and output voltage range, as well as regulate the output current. By using a synchronous rectifier in the output stage, the board is able to improve power conversion efficiency at heavy load conditions. The board also uses a highly efficient voltage-mode control method to optimize output voltage regulation performance.

At start-up, the MAX20003ATPA/V+C2 performs a soft-start cycle, during which the output voltage rises gradually. Once the preset voltage is reached, the board enters normal operation, continuously regulating the output voltage. When the input voltage is higher than the output voltage, the board operates in buck mode. When the input voltage is lower than the output voltage, the board operates in boost mode.

The MAX 20003ATPA/V+C2 also offers stability and transient protection by using over-voltage, under-voltage, over-current, and short-circuit protection. The board also offers thermal protection to ensure safe operation in extreme temperature conditions. By using a high-accuracy voltage reference, the desired output voltage also remains very stable, even during dynamic load changes.

All in all, the MAX20003ATPA/V+C2 is an excellent choice for portable devices and industrial systems where high accuracy, high efficiency, and low noise are involved. Its wide input voltage range and programmable output voltage, combined with its integrated power management functions, makes it well-suited for a variety of applications, particularly in the PMIC - Voltage Regulators - DC DC Switching Regulators field.
