12A, 23V, 500kHz, ACOTTM Synchronous Buck Converter with VTT LDO for Memory Power Supply
General Description
The RT7241A provides a plete power supply for DDR3/ DDR3L/LPDDR3/DDR4 memory systems. It integrates an Advanced Constant On-Time (ACOTTM) mode synchronous Buck converter with a 1.5A sink/source tracking linear regulator.
The PWM converter provides low quiescent supply current, high efficiency, excellent transient response, and high DC output accuracy needed for stepping down highvoltage batteries to generate low-voltage chipset RAM supplies in notebook puters. The ACOTTM control scheme handles wide input/output voltage ratios with ease and provides a very fast...
