STRW6753 Datasheet Quasi-resonant Topology Primary Switching Regulator

Manufacturer: Sanken

Overview: STR-W6753 Quasi-Resonant Topology Primary Switching Regulators.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The STR-W6753 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 mode  Improved system efficiency over the entire output load by avoiding increase of switching frequency.
  • Auto-Standby mode  Lowers input power at very light output load condition.
  • Avalanche-guaranteed MOSFET  Improves system-level reliability and does not require VDSS derating.
  • 650 V / 1.70 Ω.
  • Various protections  Improved system-level reliability Continued on the next page… Package: 6-.
