CONFORMALLY SHIELDED POWER INDUCTOR AND OTHER PASSIVE DEVICES FOR 4/5G ENVELOPE TRACKER MODULES AND/OR OTHER POWER MANAGEMENT MODULES

摘要

A circuit assembly includes a printed circuit board (PCB), and a power management arrangement positioned on and electrically coupled to the PCB. The power management arrangement includes a substrate, a power management circuit chip positioned on and electrically coupled to the substrate, and a shield can positioned over the substrate and providing electromagnetic shielding for the power management chip. The circuit assembly further includes a self-shielded coil positioned on and electrically coupled to the PCB, wherein the self-shielded coil is positioned adjacent to the power management arrangement.
