Overview

The LTC3566EUF#PBF is a highly integrated power management IC (PMIC) designed specifically for Li-Ion/Polymer battery applications powered by USB. It combines a high-efficiency switching PowerPath manager, a stand-alone battery charger, and a synchronous buck regulator in a compact 4x4mm QFN package. This IC ensures seamless power transitions between a USB port, a wall adapter, and the internal battery while maintaining efficient power delivery to the system load.

Why Choose This Part

It features Bat-Track technology which optimizes the battery charger efficiency by minimizing heat dissipation. The integrated 1A buck regulator operates at high efficiency even with light loads, and the PowerPath architecture ensures the device can power up instantly even with a dead or missing battery.

Applications

Handheld Media Players
Manages power from USB or wall adapters while simultaneously charging the battery and providing a regulated rail for the processor.
Portable GPS Navigators
Utilizes the high-efficiency buck regulator to maximize battery life in compact, mobile form factors.
Industrial Handheld Terminals
Provides a robust power path management solution that prioritizes system load over battery charging when input power is limited.
