MAX17548ATJ+ Application Field and Working Principle

The MAX17548ATJ+ is a highly efficient, 9A step-down DC-to-DC switching regulator belonging to the DC-DC switching regulators category of power management ICs (PMICs). It is designed to provide a high level of efficiency across a wide range of input/output voltage combinations and adjustable switching frequency.The MAX17548ATJ+ is capable of efficiently converting voltage levels from 1.8V to 18V or beyond, with a wide range of output voltages, making it suitable for many different applications. Its integrated switching MOSFETs and floating channel NewFETs are capable of operating up to 18V, allowing for more design flexibility in high-voltage systems. Its high-speed switching frequency enables lower-sized capacitors, reducing board space. The MAX17548ATJ+ offers various features for controlling and protecting the device, providing reliable performance and monitoring for heavy-loading output applications. It includes an integrated VDD transient protection circuit to prevent over-voltage conditions in the event of an abnormal load transient. Its integrated differential remote ON/OFF monitoring pin is used to detect remote ON/OFF control, and can also be used to detect open-circuit conditions. Its fast-start pin can be set as either fixed or on/off sensing, and its adjustable soft-start pin offers smooth ramping of the output voltage. The MAX17548ATJ+ also offers adjustable mute mode, vehicle-to-vehicle protection, over-current protection, and thermal protection. The device is available in a 16-pin, 2.0 x 2.5mm Ultra Thin MLF package, making it suitable for space-constrained applications. The MAX17548ATJ+ is designed to provide high efficiency and power density. Its maximum efficiency can reach up to 96%, meaning it is well-suited for applications in which efficiency and power-conversion costs are important. Its quiescent current is as low as 40µA, allowing for significantly lower standby power compared to other DC-DC switching regulators.The MAX17548ATJ+ is suitable for a variety of applications, such as notebooks, ultrabooks, and automotive infotainment systems. With its high efficiency, robust transient protection and safety features, wide input voltage range, and compact package size, the MAX17548ATJ+ makes a great choice for power-sensitive applications. In conclusion, the MAX17548ATJ+ DC-DC switching regulator is an excellent solution for high-powered and low-power applications. Its high efficiency and power density, comprehensive safety features, and wide input voltage range make it suitable for a wide range of applications, from automotive infotainment systems to notebooks and ultrabooks.
