Resonant controller with integrated PFC from NXP Semiconductor for high efficient power supplies

NXP Semiconductors has introduced the TEA1713, a new GreenChip resonant controller with integrated Power Factor Correction (PFC), capacitive mode protection and adaptive deadtime control. The TEA1713 controller is suitable for power supplies above 90 W for LCD TVs, plasma TVs, PCs and slim line adapters, high-quality industrial and medical power supplies.

The GreenChip TEA1713 resonant half-bridge converter complies with ENERGY STAR requirements, delivering 90+ percent efficiency with only 50 percent of the power loss of a typical flyback converter for higher power applications.

The key features of the TEA1713 GreenChip resonant controller are,
Capacitive mode protection for resonant converters
Adaptive dead-time control
High frequency protection (time out)
Over-current regulation with AC sensing
Two-level over-current protection with boost voltage compensation
Burst mode standby
Two-speed soft-start mechanism
Integrated with resonant controller and power factor controller for universal mains supply operation (70V to 276 VAC)

"Adapters and power supplies are becoming slimmer than ever, even for large TV displays and desktop computers, raising significant challenges for power supply designers," said Edwin Kluter, marketing director, power solutions business line, NXP Semiconductors. "By offering an integrated resonant controller with PFC, the GreenChip TEA1713 makes it straightforward for designers to build highly efficient compact power supplies for ultra-flat notebook adapters, flat panel displays and desktop PCs. NXP's strong heritage in High Performance Mixed Signal applications, particularly lighting, has made it possible for us introduce innovations in processing resonant-type signals while offering maximum protection in a single integrated chip."
