current-mode PWMUC2844SOP-8offline converterDC-DC controller50% duty cycle

UC2844AQD8R-TUDI is an SOP-8 current-mode PWM controller intended for offline and DC-DC converter control. Its UC2844-class UVLO is 16 V on and 10 V off, and maximum duty cycle is limited to 50%.

Best for

  • Offline switch-mode power supplies requiring a 50% duty-cycle limit
  • DC-DC converters using peak current-mode control
  • Power MOSFET gate-drive applications

Avoid if

  • Applications requiring duty cycle above 50%
  • Designs unable to provide startup voltage above the UC2844 UVLO threshold
  • Projects requiring confirmed compliance or lifecycle data without further verification

Check before use

  • Verify the exact SOP-8 package footprint
  • Set peak current from the current-sense network
  • Validate slope compensation where required by the chosen topology
  • Confirm compliance and lifecycle information with the supplier
