General Description

The TPS650231 device is an integrated power management IC for applications powered by one Li-Ion or Li-Polymer cell, and which requires multiple power rails.

The TPS650231 provides three highly efficient step-down converters targeted at providing the core voltage, peripheral, I/O, and memory rails in a processor-based system.

The core converter allows for on-the-fly voltage changes through serial interface, allowing the system to implement dynamic power savings.

Key Features

1 1.7-A, 90% Efficient Step-Down Converter for Processor Core (VDCDC1).
1.2-A, Up to 95% Efficient Step-Down Converter for System Voltage (VDCDC2).
0.8-A, 92% Efficient Step-Down Converter for Memory Voltage (VDCDC3).
30-mA LDO and Switch for Real-Time Clock (VRTC).
2 × 200-mA General-Purpose LDO.
Dynamic Voltage Management for Processor Core.
Preselectable LDO Voltage Using Two Digital Input Pins.
Externally Adjustable Rese.
