ONSEMI NCP13994AADR2G Current Mode Resonant Controller, 30 V, -40 °C to 125 °C, NSOIC-16

NCP13994 is a high performance current mode resonant controller with integrated high-voltage driver for half bridge resonant converters. This controller implements 700V gate driver, simplifying layout and reducing external component count. The built?in Brown?Out input function eases implementation of the controller in all applications. In applications where a PFC front stage is needed, this features a dedicated output to drive the PFC controller. This feature together with quiet skip mode technique further improves light load efficiency of the whole application. This includes overload protection, over?current protection to prevent hard switching cycles, brown?out detection, line brown?out, line OVP, X2 cap discharge, open optocoupler detection, automatic dead?time adjust, over?voltage and over?temperature protections. Typical applications are adapters and offline battery chargers, flat panel display power converters, computing power supplies, industrial and medical power sources.

• Provides a suite of protection features allowing safe operation in any application
• Line brown?out and OVP protections, X2 cap discharge function
• Clamped output drivers, current mode control scheme
• Automatic dead?time with maximum dead?time clamp
• Enhanced start-up sequence for fast resonant tank stabilization
• Light load operation mode for improved efficiency, pin to adjacent pin/open pin fail safe
• Quiet skip operation mode for minimize transformer acoustic noise
• Off mode operation for extremely low no?load consumption
