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. 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).
