TPS65218 Power Management IC

TI's single-chip PMIC is specially designed for ARM Cortex-A8/A9 SoCs and FPGA

Image of Texas Instruments TPS65218 Power Management ICTexas Instruments' TPS65218 is a single chip power management IC, specifically designed to support the AM437x line of the Sitara processor in both portable (Li-Ion battery) and non-portable (5 V adapter) applications. The device is characterized across a –40°C to 105°C temperature range, making it suitable for a wide range of industrial applications.

TPS65218 comes in a 48-pin QFN package (6 mm × 6 mm, .4 mm pitch) and a 48-pin QFP package (7 mm × 7 mm, 0.5 mm pitch).
