UC3842current-mode PWMDIP-8offline converterDC-DC converterMOSFET driver

UC3842AN-TUDI is a DIP-8 current-mode PWM controller intended for offline and DC-DC power converters. It integrates a 5 V reference, error amplifier, current-limit comparator, and MOSFET gate-drive output.

Best for

  • Offline switched-mode power supplies
  • DC-DC converters using current-mode control
  • Through-hole power-control designs

Avoid if

  • A confirmed RoHS, REACH, lifecycle, or qualification declaration is mandatory
  • A surface-mount-only assembly is required

Check before use

  • Confirm the exact DIP-8 mechanical footprint
  • Set peak current from the current-sense threshold and sense resistor
  • Verify startup supply voltage remains above UVLO during operation
