Description

The TPS65020 is an integrated Power Management IC for applications powered by one Li-Ion or Li-Polymer cell, and which require multiple power rails. The TPS65020 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 TPS65020 also integrates two 50 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 main battery. The two 50-mA LDO voltage regulators are intended for use with the SDRAM and PLL power supply in a Intel PXA270 based system. The serial interface is used for dynamic voltage scaling of the core voltage,masking interrupts, or for dis/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 TPS65020 incorporates a push button debounced input and latched output for implementation of a push-button turn-on feature, typically required in smartphones or wireless PDAs.
