SC1936C - Off-Line CV/CC QR Flyback Switcher

Download the SC1936C datasheet PDF. This datasheet also covers the SC1933C 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.

General Description

SC1933C/SC1936C dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size.

SC1933C/SC1936C incorporates primary and secondary controllers and safety-rated feedback into a single IC.

Key Features

  • Open SR FET-gate detection.
  • Fast input line UV/OV protection Full Safety and Regulatory Compliance.
  • Reinforced isolation.
  • Isolation voltage >4000 VAC.
  • 100% production HIPOT testing.
  • UL1577 and TUV (EN60950) safety approved.
