Introduction

AI Translation

TPS652170 is a single-chip PMIC specifically designed to power the AM335x ARM Cortex-A8 processor in portable and 5V line-powered applications. This PMIC integrates a linear battery charger (supporting single-cell Li-Ion and Li-Polymer batteries), dual-input power path, three buck converters, four LDO regulators, and a high-efficiency boost converter capable of driving two LED strings of up to 10 LEDs each. The system can be powered by any combination of a USB port, 5V AC adapter, or Li-Ion battery. Rated for an operating temperature range of -40°C to +105°C, this device is well-suited for industrial applications. Three high-efficiency 2.25MHz buck converters supply the system with core voltage, memory, and I/O voltages.
