® RT6203B 5A, 18V, 700kH- ACOTTM Synchronous Step-Down Converter with VID Control General Description The RT6203B is an adaptive on-time mode synchronous Buck converter. The main control loop of the RT6203B uses an adaptive on-time mode control which provides a very fast transient response with no external components. The RT6203B operates from 4.5V to 18V VIN input. After the initial power-up, the output voltage can be changed by codes sent into the IC via an I2C compatible VID control bus. T
