TPS65023QRHARQ1

电源管理IC，适用于锂离子电池供电系统 POWER MANAGEMENT IC FOR LI-ION POWERED SYSTEMS

Description

The TPS65023-Q1 device is an integrated power management integrated circuit IC for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65023-Q1 device provides three highly efficient, step-down converters targeted at providing the core voltage, peripheral, input and output I/O, and memory rails in a processor-based system. The core converter allows for on-the-fly voltage changes through a serial interface, allowing the system to implement dynamic power savings. All three step-down converters enter a low-power mode at light load for maximum efficiency across the widest possible range of load currents.
