The RT7294C is a synchronous step-down converter with Advanced Constant On-Time (ACOT®) mode control. The ACOT® provides a very fast transient response with few external components. The low impedance internal MOSFET supports high efficiency operation with wide input voltage range from 4.3V to 18V. The proprietary circuit of the RT7294C enables to support all ceramic capacitors.
