Texas Instruments' TPS65217 are single-chip power management ICs specifically designed to support applications in portable and 5 V, non-portable applications. They provide a linear battery charger for single-cell Li-ion and Li-polymer batteries, a dual-input power path, three step-down converters, four LDOs, and a high-efficiency boost converter to power two strings of up to ten LEDs each. The system can be supplied by any combination of USB port, 5 V AC adaptor, or Li-Ion battery. These devices are 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 provide the core voltage, memory, and I/O voltage for a system.
