Qorvo has introduced an intelligent RF power control solution for smart home appliances such as AC-powered fans and compressors.
Qorvo claims the PAC5556 power appliance controller (PAC) can reduce bill of materials by as much as 35% and improves performance, reliability and energy efficiency in brushless DC motor and permanent synchronous motor (PMSM) control appliances.
IHS Markit forecasts the global smart appliance market is expected to grow by 74% this year to 155 million shipments up from 89 million smart home appliances shipped in 2018.
The power controller features a 150 MHz ARM Cortex-M4F digital signal processor with 128 kB flash and integrates a 600 V N-channel DC/DC buck controller and signal conditioning components. The power management supplies all the voltage rails for the system including the 12 V or 15 V gate driver supply for MOSFETs or insulated gate bipolar transistors (IGBTs).
