Product Information STR-W6700 Series Off-Line Quasi-Resonant Switching Regulators Introduction The Series STR-W6750 devices are hybrid integrated circuits (HICs) with a built-in power MOSFET and a control IC designed for quasi-resonant type switch-mode power supplies (SMPS).

In normal operation, the HIC provides high efficiency and low EMI noise with bottom-skip quasiresonant operation during light output loads.

Low power consumption is also achieved by blocking (intermittent) oscillation durin

STR-W6700 Features

* include the following: ▪ Blocking (or intermittent) oscillation operation by reducing output voltage in the standby mode. ▪ In addition to the standard quasi-resonant operation, a bottom-skip function is available for increased efficiency from light to medium load. ▪ Soft-start operation at start-up
