XL2844

MOSFETs - Single

current-mode PWMSOP-8under 50% duty cycleoffline SMPSMOSFET driver

XL2844 is an SOP-8 current-mode PWM controller intended for offline and DC-DC power conversion where a duty cycle below 50% is required.

Best for

  • Offline SMPS controllers requiring sub-50% duty cycle
  • Fixed-frequency current-mode DC-DC converters

Avoid if

  • Applications requiring duty cycles approaching 100%
  • Designs with a controller supply unable to meet the 16 V typical startup threshold

Check before use

  • Confirm UVLO thresholds for the auxiliary supply design
  • Set RT and CT for the required switching frequency
  • Validate current-sense transient filtering and peak-current limit
