W6765 - STRW6765

Datasheet Summary

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.

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-.

    STR-W6765 www.DataSheet4U.com Quasi-Resonant Topology Primary Switching Regulators 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 operation 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. The package is a fully molded TO-220, which contains the controller chip (MIC) and MOSFET, enabling output power up to 52 W with universal input or 110 W with a 230 Vac input.
