What made you select the Qorvo ACT2861 buck-boost charger as a featured product?
For this Expert Product Pick I selected the Qorvo ACT2861, a 30V, 5A buck-boost charger with integrated MOSFETs, because of its high efficiency, compact design, and seamless operation across a wide input range. One of the top challenges in designing multi-cell battery-powered systems today is managing power conversion efficiently across varying input sources, especially when size, thermal performance, and quiescent current draw are tightly constrained. The need for flexible, high-performance charging in a small footprint is critically important, whether you’re working on portable medical devices, automotive accessories, or industrial handhelds.
The ACT2861 addresses these challenges with an advanced switching algorithm that enables continuous regulation when input voltage is above, below, or equal to the battery voltage. It supports 2 to 5 cell battery packs and integrates four power MOSFETs to minimize external component count. With I2C programmability, onboard ADCs for real-time monitoring, and support for USB PD and QC standards in OTG mode, it’s a fully featured power management solution. The part also includes a low-leakage current from the battery ship mode, thermal protection, and JEITA compliance, making it ideal for complex battery-powered designs where space, flexibility, and reliability are key criteria.
