The RT6301C/RT6301CH/RT6301D/RT6301DH is an integrated power management IC solution for LPDDR5 and LPDDR5X memory. This device provides two single buck voltage regulators VDD2 (RT6301C/ RT6301CH:1.065V/8A, RT6301D/RT6301DH:1.05V/8A) and VDDQ (0.52V or 0.32V/3A), and one load switch VDD1 (1.8V/1A). The RT6301C/RT6301CH/RT6301D/RT6301DH adopts Advanced Constant On-Time (ACOT®) control architecture that provides ultra-fast transient response and further reduces the number of external components. In steady states, the ACOT® operates at a nearly constant switching frequency across line, load, and output voltage ranges, and simplifies the EMI filter design.The RT6301C/RT6301CH/RT6301D/RT6301DH operates in diode emulation mode (DEM) under the light load condition, offering optimal light load efficiency. It also supports multiple operational modes, S0, S3, and S4/5, controlled by the EN/EN_VDDQ control inputs. The RT6301C/RT6301CH/RT6301D/RT6301DH provides full protection functions, including the cycle-by-cycle current limit, OVP, UVP, input UVLO, and OTP.All functions are integrated in a WQFN-19L 3x3 (FC) package. The recommended junction temperature range is -40°C to 125°C.
