Product Details
__
The NCP1631 integrates a dual MOSFET driver for interleaved PFC applications. Interleaving consists of paralleling two small stages in lieu of a bigger one, more difficult to design. This approach has several merits like the ease of implementation, the use of smaller components or a better distribution of the heating. Also, Interleaving extends the power range of Critical Conduction Mode that is an efficient and cost−effective technique (no need for low trr diodes). In addition, the NCP1631 drivers are 180° phase shift for a significantly reduced current ripple. Housed in a SOIC16 package, the circuit incorporates all the features necessary for building robust and compact interleaved PFC stages, with a minimum of external components.
General Features
• Near−Unity Power Factor
• Substantial 180° Phase Shift in All Conditions Including Transient Phases
• Frequency Clamped Critical Conduction Mode (FCCrM) i.e., Fixed Frequency,
Discontinuous Conduction Mode Operation with Critical Conduction Achievable in
Most Stressful Conditions
• FCCrM Operation Optimizes the PFC Stage Efficiency Over the Load Range
• Out−of−phase Control for Low EMI and a Reduced rms Current in the Bulk
Capacitor
• Frequency Fold−back at Low Power to Further Improve the Light Load
Efficiency
• Accurate Zero Current Detection by Auxiliary Winding for Valley Turn On
• Fast Line / Load Transient Compensation
• High Drive Capability: −500 mA / +800 mA
• Signal to Indicate that the PFC is Ready for Operation (“pfcOK” Pin)
• VCC Range: from 10 V to 20 V
Typical Applications
• Computer Power Supplies
• LCD / Plasma Flat Panels
• All Off Line Appliances Requiring Power Factor Correction
