Description

DESCRIPTION
The TPS650250 is an integrated Power Management IC for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS650250 provides three highly efficient,
step-down converters targeted at providing the core voltage, peripheral, I/O and memory rails in a
processor based system. All three step-down converters enter a low power mode at light load for
maximum efficiency across the widest possible range of load currents. The converters can be forced into fixed frequency PWM mode by pulling the MODE pin high.
FEATURES
• 1.6A, 97% Efficient Step-Down Converter for System Voltage (VDCDC1)
– 3.3V or 2.8V or Adjustable
• 0.8A, up to 95% Efficient Step-Down Converter for Memory Voltage (VDCDC2)
– 1.8V or 2.5V or Adjustable
• 0.8A, 90% Efficient Step-Down Converter for Processor Core (VDCDC3)
• adjustable output voltage on VDCDC3
• 30mA LDO for Vdd_alive
• 2 × 200mA General Purpose LDOs (LDO1 and LDO2)
• Dynamic Voltage Management for Processor Core
• LDO1 and LDO2 Voltage Externally Adjustable
• Separate Enable Pins for Inductive Converters
• 2.25MHz Switching Frequency
• 85µA Quiescent Current
• Thermal Shutdown Protection
APPLICATIONS
• Cellular/Smart Phone
• GPS
• Digital Still Camera
• Split Supply DSP and µP Solutions
• Samsung ARM-Based Processors, etc.
