The TL3844D-8 from Texas Instruments is a current-mode PWM controller designed for off-line and DC-to-DC fixed-frequency applications. It features a wide operating voltage range of 10V to 30V and can operate at frequencies up to 500kHz, with a maximum duty cycle of 48%.
This controller integrates several features necessary for efficient power management, including low start-up current, automatic feed-forward compensation, pulse-by-pulse current limiting, and undervoltage lockout with hysteresis. The output is a high-current totem-pole type, and the device is designed to be interchangeable with UC2842 and UC3842 series controllers.
The TL3844D-8 is housed in an 8-pin SOIC package, suitable for surface mount applications. It operates within a temperature range of 0°C to 70°C. Note that this part is obsolete and no longer in production, with TL3844DR-8 listed as a potential replacement with upgraded functionality.
