Block diagram-wise: The converter is just the part we saw earlier. The divider is optional but should get the expected output (5V in this case) down to the reference voltage, whatever that is.

National 5; Practical electrical and electronic circuits Voltage dividers. Measurement and analysis of current and voltage in simple circuits allows us to formulate rules and predict unknown values.
