RT5028C
PMIC for Industrial Application
General Description
The RT5028C is a highly-integrated low-power high-
performance analog SOC with PMIC in one single chip
designed for Industrial applications.
The RT5028C includes four synchronous step-down DC/
DC converters and eight LDOs for system power.
The RT5028C also embeds one EEPROM (MTP) for
setting sequence and timing etc.
Additionally, the RT5028C PMIC also includes one IRQ
report.
