Product Information STR-X6700 Series Off-Line Quasi-Resonant Switching Regulators Introduction The STR-X6700 series integrates a quasi-resonant control IC and a MOSFET with avalanche guarantee.
In normal operation, the device provides high efficiency and low EMI noise with bottom-skip quasi-resonant operation during light output loads.
Low power consumption is also achieved by Auto-standby mode (not available in the STR-X6729, STR-X6759N, or STR-X6768N) or manual standby mode (external trigger)
STRX6750 Features
* include the following: ▪ Auto standby mode (burst oscillation) or manual standby mode (UVLO intermittent oscillation) in the standby mode. ▪ In addition to the standard quasi-resonant operation, a bottom-skip mode is available for increased efficiency from light to medium load. ▪ Soft-start operati
