Qorvo ACT2861QI 30V Buck-Boost Charger

Qorvo ACT2861QI 30V Buck-Boost Charger is designed with four integrated MOSFETs and On-The-Go (OTG) function. This buck-boost charger offers a high efficiency, low-component-counts, compact solution for two- to five-cell battery-charging applications. Qorvo ACT2861QI buck-boost charger operates from 3.9V to 29V input voltage range. This charger reduces input current in shipping, shutdown, and standby for applications that are sensitive to battery-powered devices. Qorvo ACT2861QI 30V Buck-Boost Charger is available in 32-pin configuration and 4mm x 4mm QFN package. Typical applications include a multi-cell battery charger, car charger, power bank, 24V industrial applications, DC UPS, and solar-powered devices.
