对于锂离子电源管理IC供电系统 Power Management ICs for Li-Ion Powered Systems

Description

The TPS65024x devices are integrated power management ICs for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65024x provide three highly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O, and memory rails in a processor-based system.

Features

• 1.6-A, 1.0-A, or 0.8-A, 97% Efficient Step-Down Converter for System Voltage VDCDC1

  – 3.3 V or 2.80 V or Adjustable

• 1.6-A, 1.0-A, or 0.8-A, up to 95% Efficient Step-Down Converter for Memory Voltage VDCDC2

  – 1.8 V or 2.5 V or Adjustable

• 0.8-A, 90% Efficient Step-Down Converter for Processor Core VDCDC3

• Two Selectable Voltages for VDCDC3
