The TL3843D is a current-mode PWM controller designed for off-line and DC-to-DC converter applications. It features a low start-up current of less than 1mA, making it efficient for power management. The device includes automatic feed-forward compensation, pulse-by-pulse current limiting, and enhanced load-response characteristics. It is equipped with an undervoltage lockout function that incorporates hysteresis, as well as double-pulse suppression to improve performance. The high-current totem-pole output stage is suitable for driving N-channel MOSFETs and is designed to source or sink high peak currents. The TL3843D operates at a frequency of 500kHz and is compatible with the UC2842 and UC3842 series, allowing for easy integration into existing designs. The product is available in a 14-pin SOIC package.
