RT5028
Integrated PMIC with 4-Channel Synchronous Buck
Converters, 8 LDOs, and MTP Non-Volatile Memory for
Industrial Applications
General Description
The RT5028 is a highly-integrated low-power high-
performance analog SOC with PMIC in one single chip
designed for Industrial applications.
The RT5028 includes four synchronous step-down DC-
DC converters and eight LDOs for system power.
The RT5028 also embeds one EEPROM (MTP) for setting
sequence and timing etc.
Additionally, the RT5028 PMIC also includes one IRQ
report.
