1.7 A, 90% Efficient Step-Down Converter for
Processor Core (VDCDC1)
The TPS65023, TPS65023B is an integrated Power
Management IC for applications powered by one
1.2 A, Up to 95% Efficient Step-Down
Li-Ion or Li-Polymer cell, and which require multiple
Converter for System Voltage (VDCDC2)
power rails. The TPS65023, TPS65023B provides
1.0 A, 92% Efficient Step-Down Converter for
three highly efficient, step-down converters targeted
Memory Voltage (VDCDC3)
at providing the core voltage, peripheral, I/O and
30 mA LDO/Switch for Real Time Clock (VRTC)
memory rails in a processor based system. The core
converter allows for on-the-fly voltage changes via
2 × 200 mA General-Purpose LDO
serial interface, allowing the system to implement
