n The RT6363 is a 3.5A, high-efficiency, peak current mode control asynchronous step-down converter. The device operates with input voltages from 4V to 60V. The device can program the output voltage between 0.8V to VIN. The low quiescent current design with the integrated low RDS(ON) of high-side MOSFET achieves high efficiency over the wide load range. The peak current mode control with simple external compensation allows the use of small inductors and results in fast transient response and good loop stability. The wide switching frequency of 100kHz to 2500kHz allows for efficiency and size optimization when selecting the
