The RT6300B/RT6300BH is an integrated power management IC solution for LPDDR5 and LPDDR5X memory. This device provides two single buck voltage regulators VDD2H (1.05V/8A) and VDDQ (0.52V or 0.32V/3A), one LDO VDD2L (0.92V/1.5A), and one load switch VDD1 (1.8V/1A). The RT6300B/RT6300BH supports VDD2L and 1-bit VID to dynamically adjust the VDDQ output voltage, thus satisfying the requirements of LPDDR5/5X DVFSC and DVFSQ applications.The RT6300B/RT6300BH 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 RT6300B/RT6300BH 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 RT6300B/RT6300BH 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.
