What are the key features of LTC4355IDE#PBF?
- 2-channel positive high-voltage ideal diode-OR controller replaces Schottky diodes with MOSFETs for significantly lower voltage drop and power loss
- 14-pin SON (Small Outline No-lead) package provides compact footprint with reduced parasitic inductance for high-frequency power switching designs
- eFuse functionality with automatic forward current control enables safe power bus ORing in redundant server and telecom power architectures
What is LTC4355IDE#PBF used for?
The LTC4355IDE#PBF ideal diode-OR controller is used in redundant power supply systems for servers, telecommunications equipment, and industrial power architectures where two power sources must be ORed together with minimal power loss. Its 2-channel MOSFET-based ORing eliminates the 0.3 V to 0.5 V forward voltage drop of conventional Schottky diodes, improving efficiency in 12 V and 48 V dual-feed power distribution systems.

Frequently Asked Questions
How does LTC4355IDE#PBF improve efficiency over Schottky diodes in redundant power supply ORing circuits?
The LTC4355IDE#PBF drives an external N-channel MOSFET as an ideal diode, reducing the ORing voltage drop from the typical 0.3 V to 0.5 V of Schottky diodes to under 50 mV at full load current. At 10 A load current, this eliminates 3 W to 5 W of heat dissipation per channel compared to Schottky ORing, improving overall power supply efficiency in 12 V redundant server and telecom power systems.
Which high-availability server and telecom power architectures benefit from LTC4355IDE#PBF 2-channel ORing control?
LTC4355IDE#PBF suits 1+1 and N+1 redundant power supply architectures in blade servers, rack-mount network switches, and central office telecom equipment where two 12 V or 48 V power feeds must be combined without single-point failure risk. Its 2 independent channels support dual-feed ORing on the same IC, simplifying BOM and PCB layout versus separate single-channel ORing controllers in high-availability designs requiring continuous uptime.
What external MOSFET requirements does LTC4355IDE#PBF impose for proper ideal diode-OR operation?
The LTC4355IDE#PBF requires external N-channel MOSFETs rated for the full bus voltage and maximum load current of the ORing circuit. For a 12 V bus at 20 A per channel, the MOSFET should have a drain-source voltage rating of at least 20 V, on-resistance below 10 mΩ for low drop, and gate threshold voltage compatible with the LTC4355's gate drive output. The SON-14 package of the controller minimizes PCB area alongside the MOSFET in the 2-channel ORing stage.
