RT5028D

Integrated PMIC with 4-Channel Synchronous Buck Converters, 8 LDOs, and MTP Non-Volatile Memory for Industrial Applications

The RT5028D is a highly-integrated low-power high-performance analog SOC with PMIC in one single chip designed for Industrial applications.

The RT5028D includes four synchronous step-down DC-DC converters and eight LDOs for system power.

The RT5028D also embeds one EEPROM (MTP) for setting sequence and timing etc.

Additionally, the RT5028D PMIC also includes one IRQ report.
