during the on-state and to A synchronous buck converter produces a regulated voltage that is lower than its input voltage and can deliver high current while minimizing power loss. For a diode drop, Vsw and Vsw,sync may already be known, based on the properties of the selected device. Another technique is to insert a small resistor in the circuit and measure the voltage across it. Please clear your search and try again. Beginning with the switch open (off-state), the current in the circuit is zero. L This is why this converter is referred to as step-down converter. Synchronous Buck Converter Basics The synchronous buck converter is straightforward inconcept, and is used heavily in consumer electronics. Cancel Save Changes The LMR33630 provides exceptional efficiency and accuracy in a very small solution size.
