Introduction General Product Information The RT7295C 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 RT7295C enables to support all ceramic capacitors. The output voltage can be adjusted between 0.6V and 8V. The RT7295C also provides output under voltage protection and thermal shutdown protection. The low current (1.5V) to enable operation or low (
