RTQ5132

DDR5 Client VR on DIMM PMIC

RTQ5132
New

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.
