The UC3843AN is a high-performance, current-mode PWM controller designed for off-line and DC-to-DC converter applications. This IC offers excellent load response, under-voltage lockout with hysteresis, and double pulse suppression.

It operates at a frequency of up to 500kHz and features pulse-by-pulse current limiting for enhanced protection. With a low startup current of less than 0.5mA, the UC3843AN is ideal for systems requiring efficient power regulation. It’s housed in an 8-pin DIP package, providing easy integration into circuit designs.

Key Features :

  • Optimized for off-line and DC-to-DC converters.
  • Low start-up current (<0.5mA) for energy-efficient designs.
  • High-frequency operation up to 500kHz.
  • Pulse-by-pulse current limiting for enhanced protection.
  • Under-voltage lockout with hysteresis to prevent erratic startup.
  • Double pulse suppression for stable operation under varying loads.
