PowerPath Controllers & Ideal Diodes, Linear Technology
Integrated Ideal Diode controllers offer significant advantages over the use of discrete diodes in applications where forward voltage losses must be minimized such as diode-ORing of low voltage DC supplies. Some of these devices from Linear Technology include on-chip MOSFETs which take the place of conventional diodes with significantly reduced losses.
