RT6320 12A, 23V Synchronous Step-Down Converter with 3.3V/5V LDO General Description The RT6320 family are high efficiency synchronous step-down DC-DC converters with pseudo constant switching frequency of 500kHz and deliver up to 12A output current. The RT6320B/C and RT6320BH/CH operate from 4.5V to 23V input voltage. The output voltage of RT6320B/BH is fixed to 3.3V. The input voltage of RT6320C/CH ranges from 5.2V to 23V and the output voltage of RT6320C/CH is fixed to 5.1V. The RT6320 adopts Advanced Constant On-Time (ACOT® ) control architecture that provides ultra-fast transient response and further reduces the external component count.
