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.
