RT6338E/EH 8A, 23V Synchronous Step-Down Converter with 3.3V LDO General Description The RT6338E/EH family are high efficiency synchronous step-down DC-DC converters with pseudo constant switching frequency 500kHz and deliver up to 8A output current. The RT6338E/EH operate from 4.5V to 23V input voltage. The output voltage of RT6338E/EH is fixed to 3.36V output voltage. The RT6338E/EH adopts Advanced Constant On-Time (ACOT® ) control architecture that provides ultra-fast transient response and further reduces the external component count. In steady states, the ACOT® operates at nearly constant switching frequency over line, load and output voltage ranges and makes the EMI filter design easier.
