RTQ5119A DDR5 VR on DIMM PMIC General Description The RTQ5119A is an integrated solution for DDR5 R/LRDIMM and NVDIMM power management IC. This device provides 4 single Buck voltage regulators (SWA, SWB, SWC and SWD) and 3 LDOs (VLDO_1.0V, VLDO_1.8V and VBIAS). Among the four voltage regulators, the SWA and SWB can operate either in single phase mode or dual phase mode. Moreover, the RTQ5119A supports selectable interface (I2C or I3C Basic) to fit various application environment. A complete protection mechanism is also embedded for safe power distribution and the corresponding fault events can be recorded by the registers as well as CAMP and GSI_n open-drain indicators. The RTQ5119A is available in a VQFN-35L.5x5-FC package.
