RTQ5115-QA
Integrated PMIC with 4-Channel Synchronous Buck
Converters, 8 LDOs, and MTP Non-Volatile Memory for
Industrial and Automotive Applications
General Description
The RTQ5115 is a highly-integrated low-power high-
performance analog SOC with PMIC in one single chip
designed for industrial/automotive applications.
The RTQ5115 includes four synchronous step-down DC-
DC converters and eight LDOs for system power.
The RTQ5115 also embeds one EEPROM (MTP) for
setting sequence and timing etc.
Additionally, the RTQ5115 PMIC also includes one IRQ
report.
