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. There are special codes which can be used to program current limit level and thermal shutdown level. Shutdown and startup can be also programmed by special codes. The device also features an adjustable soft-start time. Output voltage is adjustable by resistor divider through the FB pin between 0.8V to 8V.
