Texas Instruments TPS652170 single-chip PMIC is specially created to power the AM335x ARM Cortex-A8 processor in portable and 5V line-powered applications. The PMIC device provides a linear battery charger for single-cell Li-ion and Li-polymer batteries, dual-input power path, three step-down converters, four LDO regulators, and a high-efficiency boost converter to power two strings of up to ten LEDs each. The system can be supplied by a combination of USB port, 5VAC adaptor, or Li-Ion battery.
The device is characterised across a –40C to +105C temperature range which makes it fitting for industrial applications. Three high-efficiency 2.25MHz step-down converters can achieve the core voltage, memory, and I/O voltage for a system. The device is supplied in a 48-pin leadless package (6mm x 6mm VQFN) with a 0.4mm pitch.
Typical applications include Sitara AM335x processor power, portable navigation systems, tablet computing, and 5V industrial equipment.
