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.
The TPS650250 also integrates two general purpose 200mA LDO voltage regulators, which are enabled with an external input pin. Each LDO operates with an input voltage range between 1.5V and 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. Additionally there is a 30mA LDO typically used to provide power in a processor based system to a voltage rail that is always on. TPS650250 comes in a small 5mm x 5mm 32-pin QFN package (RHB).
