TPS650241
Description
The TPS65024x devices are integrated power management ICs for applications powered by one LiIon 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.
Key Features
- 1 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 StepDown 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)
