RT6222C/D  
2A, 18V, 1.4MHz ACOTTM Synchronous Step-Down Converter  
General Description  
Features  
4.3V to 18V Input Voltage Range  
The RT6222C/D is a synchronous step-down converter  
withAdvanced Constant On-Time (ACOTTM) control mode.  
TheACOTTM 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 RT6222C/Denables to support all ceramic capacitors.  
The output voltage can be adjusted between 0.6V and 8V.
