UC3846N(XBLW)

Component

PWM controllercurrent-mode controlpush-pullDIP-16power supply

UC3846N(XBLW) is a DIP-16 current-mode PWM controller with complementary push-pull outputs, a 5.1 V reference, current sensing, soft start, shutdown, synchronization, and UVLO.

Best for

  • Inverter power supplies
  • Push-pull switching converters
  • UPS and DC/DC power supplies

Avoid if

  • A controller with integrated power MOSFETs is required
  • Verified lifecycle or compliance documentation is mandatory but unavailable

Check before use

  • Supply and output-stage voltage limits
  • RT/CT oscillator frequency and dead time
  • Current-sense gain and peak-current limit
  • Package thermal performance
