The RTQ5162 is an integrated power management IC designed for DDR5 SODIMM, UDIMM, CSODIMM, and CUDIMM applications. This device provides three buck converters (SWA, SWB, and SWC) and two LDOs (VLDO_1.0V and VLDO_1.8V). The voltage regulators, SWA and SWB can operate in either single-phase or dual-phase mode. Additionally, the RTQ5162 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 the PWR_GOOD and GSI_n open-drain indicators. \The RTQ5162 is available in a WQFN-28L 3x4 (FC) package. The recommended junction temperature range is from -40°C to 125°C.
