●The TPS65022 is an integrated Power Management IC for applications powered by one Li-Ion or Li-Polymer cell, and which require multiple power rails. The TPS65022 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 TPS65022 also integrates 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 default output voltage of the LDOs can be digitally set to 4 different voltage combinations using the DEFLDO1 and DEFLDO2 pins.
●The serial interface can be used for dynamic voltage scaling, masking interrupts, or for disabling, enabling, and setting the LDO output voltages. The interface is compatible with the Fast/Standard mode I2C specification, allowing transfers at up to 400 kHz. The TPS65022 is available in a 40-pin (RHA) VQFN package, and operates over a free-air temperature of –40°C to 85°C.
