The TPS65023 Multi-rail Power Supply IC realizes all necessary features to supply the OMPA3630 processor. The TPS65023 is an integrated Power Management Integrated Circuit suited for applications powered by one Li-Ion or Li-Polymer cell requiring multiple power rails. It provides three highly efficient 1500 mA, step-down dc-to-dc converters, two general purpose 200 mA Low-Drop-out voltage regulators (LDO) and one 30 mA Real Time Clock RTC LDO.
