Product Overview

The TPS650250RHBT 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. The TPS650250 also integrates two general-purpose 200mA LDO voltage regulators, which are enabled with an external input pin. Both LDOs operate with an input voltage range from 1.5 to 6.5V, allowing them to be supplied from one of the step-down converters or directly from the battery. The output voltage of the LDOs can be set with an external resistor divider for maximum flexibility.
  • 1.6A, upto 97% Efficient step-down converter for system voltage (VDCDC1)
  • 800mA, 95% Efficient step-down converter for memory voltage (VDCDC2)
  • 800mA, 90% Efficient step-down converter for processor core (VDCDC3)
  • Adjustable output voltage on VDCDC3
  • 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
