STR-W6700 datasheet



The STR-W6700 series products are power ICs for quasi-resonant type switching power supplies, incorporating a power MOSFET and a controller IC, The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation and the  bottom-skip quasi-resonant operation.

The device series products are the different package (TO-3PF) versions.


The operation mode switching with three steps according to load conditions achieves the
optimal high efficiency and low noise power supply systems across the full load range.
(The confirmation of product number is necessary because some functions are different
in each product.)
