NCP1397B Datasheet | onsemi

High Performance Resonant Mode Controller with Integrated High-Voltage Drivers NCP1397A/B, NCV1397A/B 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 ponent count. With its unique architecture, including a 500 k Hz 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 overe shoot through current. Features - High- Frequency Operation from 50 k Hz up to 500 k Hz - 600 V High- Voltage Floating Driver - Adjustable Minimum Switching Frequency with 3% Accuracy - Adjustable Deadtime from 100 ns to 2 ms. - 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 m A - 1 A/0.5 A Peak Current Sink/Source Drive Capability - mon Collector Optocoupler Connection for Easier ORing - Optional mon 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 Ro HS pliant DATA SHEET .onsemi.
