Product Description

DESCRIPTION:

• The STR-S5707 and STR-S5708 are specifically designed to meet the requirement for increased integration and reliability in off-line quasi resonant flyback converters with indirect feedback. Each device incorporates the primary control and proportional drive circuit with a third-generation high-voltage bipolar switching transistor.
