The RT6301A is an integrated power management IC solution for LPDDR5 and LPDDR5X memory. This device provides two single buck voltage regulators VDD2 (1.065V/8A) and VDDQ (0.52V/3A), and one load switch VDD1 (1.8V/1A).The RT6301A 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 RT6301A 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 RT6301A 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.
