Overview
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 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 mA • 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 www.
