A synchronous buck converter produces a regulated output voltage that is lower than its input voltage while delivering high levels of efficiency and only taking up a small amount of board real estate (thanks to the integration of both high-side and low-side MOSFETs, eliminating the need for external diode components). These devices are used in equipment that is targeted at a broad spectrum of different markets - including consumer, communications, computing, industrial, automotive, etc. Diodes offer an expansive array of high-performance buck converters with input voltages up to 40 V and output voltages down to 0.6 V being supported at different current levels.
