Linear Technology introduces the LTC4352, a 0V to 18V ideal diode controller that enables low loss ORing of multiple power sources with minimal disturbance to supply voltages. The LTC4352 regulates the forward voltage drop across an external N-channel MOSFET to ensure smooth current transfer between supplies in diode-OR applications. In low voltage systems a slow handoff between controllers results in a voltage droop during supply switchover. The fast 500ns turn-on time and carefully architected LTC4352 ensures smooth switchover from one path to the other without oscillation |
