INN3270C - Off-Line CV/CC QR Flyback Switcher

Download the INN3270C datasheet PDF. This datasheet also covers the INN3264C variant, as both devices belong to the same off-line cv/cc qr flyback switcher family and are provided as variant models within a single manufacturer datasheet.

Description

The InnoSwitch™3-CP family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size.

The InnoSwitch3-CP family incorporates primary and secondary controllers and safety-rated feedback into a single IC.

Features

  • Secondary switch or diode short-circuit protection.
  • Open SR FET-gate detection.
  • Fast input line UV/OV protection Optional Features.
  • Cable-drop compensation with multiple settings.
  • Variable output voltage, constant current profiles.
  • Auto-restart or latching fault response for output OVP/UVP.
  • Multiple output UV fault thresholds.
  • Latching or hysteretic primary over-temperature protection Full Safety and Regulatory Compliance.
