UC2845ACurrent-mode PWMSOP-8Offline converterDC-DC converter50% duty cycle

UC2845AQD8R-TUDI is an SOP-8 current-mode PWM controller for offline and DC-DC power converters. It is the low-UVLO, 50%-maximum-duty-cycle UC2845A variant.

Best for

  • Offline current-mode power converters
  • DC-DC converters using a power MOSFET
  • Designs requiring approximately 50% maximum duty cycle

Avoid if

  • A duty cycle above 50% is required
  • Supply startup voltage cannot reach the UC2845A UVLO turn-on threshold
  • Compliance or qualification evidence is mandatory but unavailable

Check before use

  • Verify RT and CT for the required switching frequency
  • Set peak current using the current-sense network
  • Confirm SOP-8 land pattern and ordering suffix
  • Confirm current lifecycle and compliance status with the supplier
