PRODUCTION DATA
Figure 8-1 shows a typical application circuit of the LMR664x0-Q1 synchronous buck regulator with output voltage set at 3.3 V and rated load current of 3 A. This device is designed to function over a wide range of external components and system parameters. However, the internal compensation is optimized for a certain range of external inductance and output capacitance. In this example the nominal input voltage is 12 V and ranges between 4 V and 36 V. The maximum switching frequency is set at 2.2 MHz by connecting the MODE/SYNC pin to GND, which allows for the device to operate in AUTO mode. The VOUT/FB pin is connected directly to the output voltage node which improves efficiency performance.
