TPS650250RHBT Datasheet PDF - TI

●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.
