SENZero

SENZero is a single-chip, integrated solution that enables power supply systems to comply with stringent no-load and standby power requirements (e.g., EuP Lot 6 or 7, and other efficiency standards). This device eliminates unnecessary power losses in the signal paths/channels between high-voltage rails and power supply controllers of power factor correction (PFC) and DC/DC converters. Examples include feed-forward or feedback signal paths connected to boost controllers in PFC systems and feed-forward signal paths in two-switch-forward / LLC / half- and full-bridge converters.
