DC DC Switching Controllers

Current-mode PWMSOP-850% duty cycleLow UVLOMOSFET gate drive

TL3845BDR-8-TUDI is an SOP-8 fixed-frequency current-mode PWM controller intended for offline and DC-DC converter control, with low-threshold UVLO and a 50% maximum-duty output.

Best for

  • Current-mode offline converters
  • DC-DC power converters with duty cycle at or below 50%

Avoid if

  • A controller requiring duty cycles above 50%
  • Compliance or qualification documentation is mandatory but unavailable

Check before use

  • Verify oscillator timing components for the required switching frequency
  • Check gate-drive current and output-voltage capability at the intended VCC
  • Confirm the exact package ordering code with the supplier
