DC DC Switching Controllers

PWM ControllerCurrent ModeTISMPS

The UC3844AD8TR is a fixed-frequency, current-mode PWM controller optimized for offline and DC-to-DC converter applications, featuring a 50% maximum duty cycle and 1A output drive capability.

Best for

  • Offline AC/DC power supplies
  • DC/DC converters
  • Industrial power modules

Avoid if

  • Applications requiring >50% duty cycle (use UC3842/43 instead)
  • Very low-power designs where 11mA operating current is excessive

Check before use

  • UVLO thresholds
  • Gate drive requirements
  • Current sense resistor sizing
