Ideal diode controllers offer a simple low loss replacement to power Schottky diodes in high current applications. Linear Technology’s family of high power ideal diodes use N-channel MOSFETs to perform the function of a low forward voltage diode. This provides a more efficient solution and preserves precious board space by reducing the need for heat sinking. Linear control of the forward voltage drop across the MOSFET ensures smooth current delivery without oscillation, even under light loads. If a power source fails or is shorted, a fast <1μs turn-off minimizes reverse current transients. Ideal diode controllers are ideal for ORing supplies together to provide redundancy in the event of input failure or hard short. Additionally, ideal diodes can be used for output supply holdup during brief interruptions of input power.
