RT6337 9A, 23V Synchronous Step-Down Converter with 3.3V/5V LDO General Description The RT6337 family are high efficiency synchronous step-down DC-DC converters with pseudo constant switching frequency 500kHz and deliver up to 9A output current. The RT6337A/B and RT6337AH/BH operate from 4.5V to 23V input voltage. The output voltage of RT6337A/AH is programmed between 0.6V to 5.5V and RT6337B/BH is fixed to 3.3V output voltage. The input voltage of RT6337C/CH ranges from 5.2V to 23V and the output voltage of RT6337C/CH is fixed to 5.1V. The RT6337 adopts Advanced Constant On-Time (ACOT® ) control architecture that provides ultra-fast transient response and further reduces the external component count.
