The TL2844D-8 from Texas Instruments is a current mode PWM controller suitable for off-line and DC-to-DC converter applications. It operates with a voltage input range of 10V to 30V and supports topologies including Boost, Flyback, and Forward.
This controller features a maximum duty cycle of 48% and an operating frequency of up to 500kHz. It includes essential control features such as frequency control and undervoltage lockout (UVLO) with specified thresholds of 16V/10V. The device is housed in an 8-SOIC package, designed for surface mount.
Key internal circuits include an error amplifier and a bandgap reference. The device is optimized for low start-up current and offers pulse-by-pulse current limiting. Its output configuration is positive, and it functions as a transistor driver.
The TL2844D-8 is designed to be interchangeable with UC2842 and UC3842 series controllers, providing a robust solution for power management designs.
