The TPS65217x is a single-chip power management IC (PMIC) specifically designed to power the AM335x ARM® Cortex®-A8 processor in portable and 5-V linepowered applications. The PMIC device provides a linear battery charger for single-cell Li-ion and Lipolymer batteries, dual-input power path, three stepdown converters, four low-dropout (LDO) regulators, and a high-efficiency boost converter to power two strings of up to 10 LEDs each. The system can be supplied by any combination of USB port, 5-V AC adaptor, or Li-Ion battery. The device is characterized across a –40°C to +105°C temperature range which makes it suitable for industrial applications. Three
high-efficiency 2.25-MHz step-down converters can providing the core voltage, memory, and I/O voltage for a system. The TPS65217x device comes in a 48- pin leadless package (6-mm × 6-mm VQFN) with a 0.4-mm pitch.

A power management integrated circuit (PMIC) is used to manage power on an electronic devices or in modules on devices that may have a range of voltages. The PMIC manages battery power charging and sleep modes, DC-to-DC conversion, scaling of voltages down or up, among others.
Power management integrated circuits (power management ICs or PMICs or PMU as unit) are integrated circuits for power management. Although PMIC refers to a wide range of chips (or modules in system-on-a-chip devices), most include several DC/DC converters or their control part.
