Freescale Semiconductor has expanded its system power management portfolio to support key members of its embedded networking products. Available now, the highly efficient VR500 regulator is specifically designed to enable comprehensive system solutions leveraging Freescale’s QorIQ Layerscape LS1 processors for a variety of applications including secure infrastructure equipment for the Internet of Things.
Integrated into Freescale’s recently announced LS1021A IoT Gateway , the VR500 is designed for a variety of 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 VR500 system power management solution allows customers to quickly and more precisely configure their systems to meet the unique voltage, current and timing needs of individual applications. It offers dynamic regulator control via an I2C 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. Five integrated LDOs provide the flexibility needed to power peripherals while significantly reducing bill of materials costs and package sizes.
VR500 key features:
- Vin = 3.3 Vbus Supply (2.8 V to 4.5 V)
- Four independent buck converters
- Five user programmable LDOs
- Forced PWM/PFM or APS operation
- DDR reference
- Thermally enhanced 8 x 8 mm QFN wettable flank package
