Optimized for Use in Consumer and Industrial Applications, Built-in Inductor and MOSFET, Buck DC/DC Switching Regulator Modules

High-performance digital LSIs such as FPGAs and SoCs are increasingly used in large-scale industrial and consumer equipment, including industrial robots, cellular base stations, and semiconductor testers. Since these LSIs require higher power supply performance, such as low voltage, high precision, and complex sequence control, in proportion to their processing capacity, the difficulty of designing power supply circuits increases.

The new products are modules that contain five components (an inductor, 2 types of MOSFETs, a bypass capacitor, and a controller IC) necessary to configure a DC/DC switching regulator in a single package. Since these five components are selected and modularized with optimal patterning to maximize performance, it is easy to design power supplies up to 20 A without spending hours on component selection and layout design even for severe requirements. In addition, the availability of three different maximum currents in the same package and pin layout makes it easy to handle specification changes in the maximum current during the design process. Therefore, these products are suitable for the design of power supply circuits for high-performance digital LSIs, etc., which are difficult to design.

The range of the input voltage is from 4 V to 28 V, and the output voltage can be set arbitrarily from 0.7 V to 5.3 V using external resistors. A soft-start time adjustment function to prevent inrush current and a power good function to inform other devices of the output voltage status are also available. In addition, these products have many protective functions for reliable use…
