The RT6300A is an integrated power management IC solution for LPDDR5 and LPDDR5X memory.The RT6300A is an integrated power management IC solution for LPDDR5 and LPDDR5X memory. This device provides two single buck voltage regulators VDD2H (1.065V/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 RT6300A 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 RT6300A adopts an 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 RT6300A 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 RT6300A 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.
