STR-X6757

Package Image

Package:TO3PF-7L

The STR-X6700 series products are power ICs for quasi-resonant type switching power supplies, incorporating a power MOSFET and a controller IC, The product achieves highefficiency and low noise power supply systems by the quasi-resonant operation and the bottom-skip quasi-resonant operation.
A compact 6 pin full mold package (TO-3P, Sanken Electric designation: 3GR-X), helps realize low component count, and high performance-to-cost power supply.

 Sanken will assist you in creating a power supply trans
 design using this product. Please fill out the form with
