The TPS65024x 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. The TPS65024x also integrate two general purpose 200-mA LDO voltage regulators, which are enabled with an external input pin. 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 battery. The output voltage of the LDOs can be set with an external resistor divider for maximum flexibility. Additionally there is a 30-mA LDO typically used to provide power in a processor based system to a voltage rail that is always on. TPS65024x provide voltage scaling on DCDC3 using the DEFDCDC3 pin. This pin either needs to be connected to a logic HIGH or logic LOW level to set the output voltage of DCDC3. TPS65024x come in a small 5-mm × 5-mm 32-pin QFN package (RHB).
