RAA270005KFP General Purpose Power Management IC
The PMIC contains two types of DCDCs converters: buck and boost, two lowdropout linear regulators (LDO) and two linear trackers.
The switching frequency of boost/buck DCDCs are typical 420 kHz, 2.1 MHz respectively.
Monitor functions for the internal status are implemented. Input voltage, output of all regulators, and internal analog voltage corresponding to temperature can be monitored through ADC of MCU. And reference voltage can be monitored for testing the ADC of MCU as well.
The PMIC has sequencer circuits for controlling power-up/down, therefore any external sequencer circuits are unnecessary. And the PMIC can controlan external backup-power for MCU.
