PRODUCTION DATA
Figure 9-1 shows the schematic diagram of a synchronous buck regulator with an output voltage set at 5 V and a rated load current of 3 A. The RT resistor of 39.2 kΩ sets the switching frequency at 400 kHz.
In this example, the nominal input voltage is 12 V and ranges from 7 V to 36 V. The VOUT / FB pin is connected directly to the output voltage net which helps improve efficiency, particularly at light loads.
