ON Semiconductor NCP1399ACDR2G

Description
The NCP1399 is a high-performance current mode controller for half-bridge resonant converters. It features integrated 600 V gatedrivers, simplifying layout and reducing external component count. The built-in Brown-Out input function eases implementation in all applications. For applications requiring a PFC front stage, the NCP1399 has a dedicated output to drive the PFC controller. This feature, along with a dedicated skip mode technique, further improves light load efficiency of the entire application.
