The TPS65024x devices are integrated power management ICs for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65024x provide 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.
