Product Overview

The UC3846N is a Current Mode PWM Controller that provides all of the necessary features to implement fixed frequency, current mode control schemes while maintaining a minimum external parts count. The superior performance of this technique can be measured...
  • Automatic feed forward compensation
  • Programmable pulse-by-pulse current limiting
  • Automatic symmetry correction in push-pull configuration
  • Enhanced load response characteristics
  • Parallel operation capability for modular power systems
  • Differential current sense amplifier with wide common mode range
  • Double pulse suppression
  • 500mA (Peak) totem-pole outputs
  • ±1% bandgap reference
  • Under-voltage lockout
  • Soft-start capability
  • Shutdown terminal
  • Green product and no Sb/Br
