1 / 32 page © Semiconductor Components Industries, LLC, 2016 March, 2016 − Rev. 6 1 Publication Order Number: NCP4304/D NCP4304A, NCP4304B Secondary Side Synchronous Rectification Driver for High Efficiency SMPS Topologies The NCP4304A/B is a full featured controller and driver tailored to control synchronous rectification circuitry in switch mode power supplies. Due to its versatility, it can be used in various topologies such as flyback, forward and Half Bridge Resonant LLC. The combination of externally adjustable minimum on and off times helps to fight the ringing induced by the PCB layout and other parasitic elements. Therefore, a reliable and noise less operation of the SR system is insured. The extremely low turn off delay time, high sink current capability of the driver and automatic package parasitic inductance compensation system allow to maximize synchronous rectification MOSFET conduction time that enables further increase of SMPS efficiency. Finally, a wide operating VCC range combined with two versions of driver voltage clamp eases implementation of the SR system in 24 V output applications. Features • Self-Contained Control of Synchronous Rectifier in CCM, DCM, and QR Flyback Applications • Precise True Secondary Zero Current Detection with Adjustable Threshold • Automatic Parasitic Inductance Compensation Input • Typically 40 ns Turn off Delay from Current Sense Input to Driver • Zero Current Detection Pin Capability up to 200 V • Optional Ultrafast Trigger Interface for Further Improved Performance in Applications that Work in Deep CCM • Disable Input to Enter Standby or Low Consumption Mode • Adjustable Minimum On Time Independent of VCC Level • Adjustable Minimum Off Time Independent of VCC Level • 5 A/2.5 A Peak Current Sink/Source Drive Capability • Operating Voltage Range up to 30 V • Gate Drive Clamp of Either 12 V (NCP4304A) or 6 V (NCP4304B) • Low Startup and Standby Current Consumption • Maximum Frequency of Operation up to 500 kHz • SOIC−8 Package • These are Pb−Free Devices Typical Applications • Notebook Adapters • High Power Density AC/DC Power Supplies • Gaming Consoles • All SMPS with High Efficiency Requirements Device Package Shipping† ORDERING INFORMATION NCP4304ADR2G SOIC−8 (Pb−Free) 2,500 / Tape & Reel SOIC−8 D SUFFIX CASE 751 MARKING DIAGRAMS 4304x = Specific Device Code x = A or B A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package 1 8 4304x ALYW G G 1 8 NCP4304BDR2G SOIC−8 (Pb−Free) 2,500 / Tape & Reel 2 3 4 1 7 6 5 8 TRIG/DIS MIN_TOFF VCC MIN_TON DRV GND COMP CS †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.
