Datasheet Summary
12A, 23V Synchronous Step-Down Converter with Adjustable Output Voltage and Low Power Mode
General Description
The RT6321 is high efficiency synchronous step-down DC-DC converters with pseudo constant switching frequency 500kHz and deliver up to 12A output current. The RT6321 operates from 4.5V to 23V input voltage. The output voltage of RT6321 is programmed between 0.6V to 5.5V. The RT6321 supports low power mode (LPM) to dynamically change output voltage between target voltage and zero voltage.
The RT6321 adopts Advanced Constant On-Time (ACOT® ) control architecture that provides ultra-fast transient response and further reduces the external ponent count. In steady states,...
