General Description

The STR-W6765 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.

Key Features

Quasi-resonant topology IC  Low EMI noise and soft switching.
Bottom-skip operation  Improved system efficiency over the entire output load by avoiding increase of switching frequency.
Standby burst mode operation  Lowers input power at very light output load condition.
Avalanche-guaranteed MOSFET  Improves systemlevel reliability and does not require VDSS derating.
800 V / 1.8 Ω, 52 to 110 W (Universal/230 VAC input) Continued on the next page… Package: 6-pin TO-22.
