Nexperia NEX81915 and NEX81916
Fast turn-off dual synchronous rectifiers (SR) controller, smarter switching for cooler, more reliable conversion
NEX81915 and NEX81916 are dedicated controller ICs for synchronous rectification on the secondary side of resonant converters. Both support DCM, CCM, and CRM operation modes and feature dual driver stages for SR MOSFET control via VDS sensing, replacing Schottky diodes to enhance efficiency.
NEX81915 is optimized for standard SR control applications with reliable switching and compact integration.
NEX81916 adds extended protection and control features for more demanding power environments.
