RT6323 8A, 23V Synchronous Step-Down Converter with 2-Bit VID Control and Low Power Mode 1 General Description The RT6323 is a high-efficiency synchronous stepdown converter with a pseudo-constant switching frequency 600kHz, delivering up to 8A continuous and 10A peak output current. The RT6323 operates from 3V to 23V input voltage. It supports 2-bit VID and low power mode (LPM#) to dynamically change the output voltage to satisfy VDD_MEM applications. The RT6323 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.
