Electronic systems that receive power from an AC power source or a DC polarity-agnostic power source often employ a 4-diode rectifier. The traditional diode bridge comes with an efficiency loss due to the voltage drop generated across two conducting diodes. The voltage drop reduces the available supply voltage and dissipates significant power especially in low voltage applications. By maximizing available voltage and reducing power dissipation, the ideal diode bridge simplifies power supply design and reduces power supply cost. An ideal diode bridge also eliminates thermal design problems, costly heat sinks, and greatly reduces PC board area.

The LT4320 is designed for DC to 60Hz typical voltage rectification. Higher frequencies of operation are possible depending on MOSFET size and operating load current.
