RT5028A
PMIC for Industrial/Automotive Application
General Description
The RT5028A is a highly-integrated low-power high-
performance analog SOC with PMIC in one single chip
designed for Industrial/Automotive applications.
The RT5028A includes four synchronous step-down DC/
DC converters and eight LDOs for system power.
The RT5028A also embeds one EEPROM (MTP) for setting
sequence and timing etc.
Additionally, the RT5028A PMIC also includes one IRQ
report.
