The TL3843 Current-Mode PWM Controller from Texas Instruments is designed for off-line and DC-to-DC fixed-frequency current-mode control applications. It features a low start-up current of less than 1mA, automatic feed-forward compensation, and pulse-by-pulse current limiting, making it suitable for various switching regulator designs. The controller operates at a frequency of 500kHz and includes an undervoltage lockout with hysteresis, double-pulse suppression, and a high-current totem-pole output stage capable of driving N-channel MOSFETs. The device is available in an 8-pin SOIC package, facilitating integration into compact designs. It is also designed to be interchangeable with the UC2842 and UC3842 series, providing flexibility for engineers familiar with those products.
