Infineon 111-3038PBF: N+1 ORing Controller for −48 V Distributed Power

The Infineon 111-3038PBF is an N+1 ORing controller in 8-SOIC that drives external N-channel MOSFETs for redundant −48 V distributed power. Supply range is about 36–75 V at roughly 500 µA bias, with ~27 µs turn-on and ~130 ns turn-off delays. Ideal-diode style ORing cuts the forward drop of Schottky diodes in telecom shelves and redundant server feeds. Layout the sense and gate loops tightly and size the FETs for continuous current plus hot-swap stress. IR-heritage controllers can be lifecycle-constrained; verify Infineon status, RoHS flow (PBF), and the exact SOIC-8 land pattern before volume release.
