PRODUCTION DATA
The following figure shows the schematic diagram of a 5 V, 6 A buck regulator with a switching frequency of 2.1 MHz. In this example, the target efficiencies is 90%, based on a nominal input voltage of 12 V that ranges from 7 V to 36 V. A resistor of 6.9 kΩ, RRT, sets the free-running switching frequency at 2.1 MHz. An optional SYNC input must be limited to ±20% of the set frequency using the RT resistor.
