ШИМ-контроллер STR-W6756

            Микросхема STR-W6756 – это ШИМ-контроллер со встроенным ключом, выполненный в корпусе TO-220.

The STR-W6756 is a quasi-resonant topology IC designed for SMPS applications. It shows lower EMI noise characteristics than conventional PWM solutions, especially at greater than 2 MHz. It also provides a soft-switching mode to turn on the internal MOSFET at close to zero voltage (VDS bottom point) by use of the resonant characteristic of primary inductance and a resonant capacitor.
