7.2.2 Design 2 – High-Efficiency, 440kHz, Synchronous Buck Regulator
The following figure shows the schematic diagram of a single-output synchronous buck regulator with an output
voltage of 3.3V and a rated load current of 12A. In this example, the current is sensed using a resistor placed in
series with the output inductor. The switching frequency is set at 440kHz by resistor RT. The 3.3V output voltage
is achieved by connecting FB directly to VCC.
