Qorvo has introduced a new intelligent power control solution for reducing energy consumption, bulk, weight and noise in smart home appliances, AC-powered fans and compressors. This mixed-signal system-in-package (SiP) product can reduce bill-of-materials as well as enhance performance, reliability and energy efficiency in brushless DC (BLDC) motor and permanent magnet synchronous motor (PMSM) control applications.
The Qorvo PAC5556 Power Application Controller (PAC) delivers high power density in a compact 52-pin 10x10 QFN package. It features a 150 MHz Arm Cortex-M4F digital high-performance processor with 128 KB Flash memory and integrates a 600 V N-channel DC-DC buck controller and signal conditioning components. This 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 12 V or 15 V gate driver supply for MOSFETs or IGBTs. An additional, high-efficiency 5 V DC-DC buck converter provides power for other system peripherals.
