PRODUCTION DATA
Figure 8-2 shows the schematic diagram of a synchronous buck regulator with an output voltage set at 5V and a rated load current of 4A. In this example, the target half-load and full-load efficiencies are 94.25% and 94%, respectively, based on a nominal input voltage of 13.5V that ranges from 5V to 36V. The switching frequency is set at 2.1MHz with resistor RRT of 6.04kΩ. The BIAS input is connected to the 5V output, thus reducing IC bias power dissipation and improving efficiency performance.
