The RTQ5132 is an integrated power management IC suitable for general DDR5 SODIMM and UDIMM applications. This device provides three Buck converters (SWA, SWB, and SWC) and two LDOs (VLDO_1.0V and VLDO_1.8V). Additionally, the RTQ5132 supports a selectable interface (I2C or I3C Basic) to accommodate various application environments. A comprehensive protection mechanism is embedded to ensure safe power distribution, with the capability to record fault events in registers and signal them through PWR_GOOD and GSI_n open-drain indicators. The RTQ5132 is available in a WQFN-28L 3x4 (FC) package. The recommended junction temperature range is from -10°C to 125°C and ambient temperature range is 0°C to 85°C.
