RT5028E
Integrated PMIC with 4-Channel Synchronous Buck
Converters, 8 LDOs, and MTP Non-Volatile Memory for
Industrial Applications
General Description
The RT5028E is a highly-integrated low-power high-
performance analog SOC with PMIC in one single chip
designed for industrial applications.
The RT5028E includes four synchronous step-down DC-
DC converters and eight LDOs for system power.
The RT5028E also embeds one EEPROM (MTP) for
setting sequence and timing etc.
Additionally, the RT5028E PMIC also includes one IRQ
report.
