AC DC Converters

PWM ControllerQuasi-ResonantAC-DC

The NCP1380CDR2G is a quasi-resonant PWM controller optimized for high-power AC-DC adapters, featuring advanced valley-lockout and integrated brown-out protection.

Best for

  • High-power AC-DC adapters
  • TV power supplies
  • Set-top boxes

Avoid if

  • Applications requiring simple fixed-frequency PWM without quasi-resonant benefits.

Check before use

  • Ensure the ZCD pin resistor network is correctly calculated for your input voltage range.
