   NCP1397A/B, NCV1397A/B High Performance Resonant Mode Controller with Integrated High-Voltage Drivers The NCP1397 is a high performance controller that can be utilized in half bridge resonant topologies such as series resonant, parallel resonant and LLC resonant converters. It integrates 600 V gate drivers, simplifying layout and reducing external component count. With its unique architecture, including a 500 kHz Voltage Controlled Oscillator whose control mode permits flexibility when an ORing function is required, the NCP1397 delivers everything needed to build a reliable and rugged resonant mode power supply. The NCP1397 provides a suite of protection features with configurable settings to optimize any application. These include: auto?recovery or fault latch?off, brown?out, open optocoupler, soft?start and short?circuit protection. Deadtime is also adjustable to overcome shoot through current. Features ? High?Frequency Operation from 50 kHz up to 500 kHz ? 600 V High?Voltage Floating Driver ? Adjustable Minimum Switching Frequency with ±3% Accuracy

Adjustable Deadtime from 100 ns to 2 s. ? Startup Sequence Via an Externally Adjustable Soft?Start ? Brown?Out Protection for a Simpler PFC Association ? Latched Input for Severe Fault Conditions, e.g. Over Temperature or OVP ? Timer?Based Input with Auto?Recovery Operation for Delayed Event Reaction ? Latched Overcurrent Protection ? Disable Input for Immediate Event Reaction or Simple ON/OFF Control ? VCC Operation up to 20 V ? Low Startup Current of 300 A ? 1 A/0.5 A Peak Current Sink/Source Drive Capability ? Common Collector Optocoupler Connection for Easier ORing ? Optional Common Emitter Optocoupler Connection ? Internal Temperature Shutdown ? NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC?Q100 Qualified and PPAP Capable ? These Devices are Pb?Free, Halogen Free/BFR Free and are RoHS Compliant Typical Applications ? Flat Panel Display Power Converters ? High Power ac?dc Adapters for Notebooks ? Computing Power Supplies
