Regulator powers IoT applications

The VR500 multi-output buck regulator enables comprehensive system solutions for secure infrastructure equipment for the Internet of Things. It helps meet the stringent functional safety requirements and reduce system power consumption for mission-critical automotive and industrial applications. The device operates from a Vin of 3.3 V, has four independent buck converters, fiver user programmable LDOs, and is packaged in an 8 x 8-mm QFN package.

The regulator suits intelligent applications that leverage the sophisticated security of the ARM-based QorIQ LS1021A processor, including mobile wireless routers, multi-function printers, network attached storage products and automatic teller machines. The configurability of the regulator allows designers to quickly configure their systems to meet the unique voltage, current and timing needs of individual applications. It offers dynamic regulator control via an I² C digital interface for programmability and dynamic voltage control, optimizing the processor’s performance and enabling easy voltage scaling. Four integrated buck converters ensure the target device has high full load efficiency, low power dissipation and integrated switching transistors.
