DescriptionThe TPS650250 device is an integrated Power
ManagementIC for applications powered by one Li-
Ionor Li-Polymer cell, which require multiple power
rails. The TPS650250 provides three highly efficient,
step-down converters targetedat providing the core
voltage, peripheral, I/O and memory rails ina
processor-based system. All three step-down
