Qorvo® Delivers Programmable Power in Smart Home Appliances

New SiP expands portfolio, reduces energy usage and PCB space, slashes BOM costs

GREENSBORO, NC – July 31, 2019 – Qorvo® (Nasdaq: QRVO), a leading provider of innovative RF solutions that connect the world, today introduced a new intelligent power control solution that significantly reduces energy consumption, bulk, weight and noise in smart home appliances, AC-powered fans and compressors. This new, mixed-signal System in Package (SiP) product can reduce bill of materials by as much as 35 percent, even as it enhances performance, reliability and energy efficiency in brushless DC (BLDC) motor and permanent magnet synchronous motor (PMSM) control applications.

“In a recent report, IHS Markit concluded there were 89 million smart home appliances shipped globally in 2018, representing about 16 percent of all large white good shipments. In 2019, the global smart appliance market is expected to grow by 74% to 155 million shipments,” said Blake Kozak, principal analyst for Smart Home and Security, IHS Markit.

The Qorvo PAC5556 Power Application Controller® (PAC) delivers extreme power density in a slim, compact 52-PIN 10×10 QFN package. It features a 150MHz Arm® Cortex®-M4F digital high-performance processor with 128kB FLASH and integrates a 600V N-channel DC/DC Buck Controller and signal conditioning components. This greatly reduces the bill of materials in high-voltage systems that do not require isolation.

The integrated power management supplies all necessary voltage rails for the system, including the 12V or 15V gate driver supply for metal-oxide-semiconductor field-effect transistors (MOSFETs) or insulated gate bipolar transistors (IGBTs). An additional, high-efficiency 5V DC/DC Buck Converter provides power for other system peripherals.

Larry Blackledge, general manager, Qorvo Programmable Power Management business unit, said, “We are continually optimizing our product designs to improve performance and increase energy efficiency. The PAC5556 expands our highly-optimized family of PAC devices that can implement BLDC and PMSM programmable motor controllers and drivers in a single, integrated package. This is a game changer for controlling and powering next-generation smart energy AC-powered appliances, devices and equipment.”

BLDC motors are seeing widespread adoption, thanks to their maintenance-free operation, longer life span, power efficiency and quieter operation. Next-generation systems that are switching from brushed DC motors to BLDCs include smart home appliances, HVAC systems, automobiles, aerospace, defense and medical devices.
