Description :

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.onsemi.com 16 1 SO−16, LESS PIN 13 D SUFFIX CASE 751AM MARKING DIAGRAMS 16 NCx1397yG AWLYWW 1 x = P (standard) or V (automotive) y = A or B A = Assembly Location WL = Wafer Lot Y = Year WW = Work Week G = Pb−Free Package PIN CONNECTIONS CSS(dis) 1 Fmax 2 Ctimer 3 Rt 4 BO 5 FB 6 DT 7 Skip/Disable 8 16 Vboot 15 Mupper 14 HB 12 VCC 11 Mlower 10 GND 9 Fault (Top View) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 26 of this data sheet.
