The TPS6505xx family of devices are integrated power management ICs for applications
powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS6505xx devices
provide two highly efficient, 2.25-MHz step-down converters targeted at providing the core voltage
and I/O voltage in a processor-based system. Both step-down converters enter a low power mode at
light load for maximum efficiency across the widest possible range of load currents. For low noise
applications the devices can be forced into fixed frequency PWM mode by pulling the MODE pin high.
The TPS6505xx devices also integrate one 400-mA LDO and two 200-mA LDO voltage regulators. Each LDO
operates with an input voltage range between 1.5 V and 6.5 V allowing them to be supplied from one
of the step-down converters or directly from the main battery.
