RTQ5115-QA

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

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.
