RT6222A - SynchronousStep-Down Converter

The RT6222A/B is a synchronous step-down converter with Advanced Constant On-Time (ACOTTM) control mode. The ACOTTM 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 18.
