    Conference Highlights

NXP architect Rob De Nie demonstrates the new DCM PFC + LLC resonant controller, based on NXP's novel cycle-by-cycle architecture (capacitive voltage control). The part will be released as a combo in a separate SO8 and SO16 package. The combo controller features very high efficiency at light load (10 % - 30 %) to be compliant with tomorrow's energy efficiency regulations (Energy Star v6, CoC tier 2, 80+ Platinum). The TEA1916 also features low no-load power below 75 mW and meets EuP lot6. The LLC resonant topology makes it easier to meet Common Mode Noise requirements and 200 % peak power requirements (compared to flyback).

Last but not least the part guarantees ease of design while supporting accurate burst mode and reduced audible noise.

The electronics industry is being driven by four mega trends that are helping shape our society: Energy Efficiency, Connected Devices, Security and Health. Connecting to these trends and enabling Secure Connections for a Smarter World, NXP Semiconductors N.V. (NASDAQ: NXPI) creates solutions for the Connected Car, Cyber Security, Portable & Wearable and the Internet of Things. Through our innovations, customers across a wide variety of industries – including automotive, security, connected devices, lighting, industrial and infrastructure – are able to differentiate their products through features, cost of ownership and/or time-to-market.
