NXP's new DCM PFC + LLC resonant controller is 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.
Feature
- Improved, easier design due to cycle-by-cycle capacitive voltage control, which is linear related to the output power
- Different modes overload range ensure the highest possible efficiency, especially at lower loads
- Low standby power performance, complying to all regulations while saving BOM cost (e.g. aux. supply can be omitted)
