The TL2844DR-8 from Texas Instruments is a current mode PWM controller suitable for off-line and DC-to-DC converters. It features a 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 for efficient power management, including automatic feed-forward compensation, pulse-by-pulse current limiting, and undervoltage lockout with hysteresis. It also offers double-pulse suppression and a high-current totem-pole output.
The TL2844DR-8 is available in an 8-SOIC package and is designed for surface mount applications. Its optimized design aims to implement fixed-frequency current-mode control schemes with a minimal number of external components, making it versatile for various power supply designs.
Key electrical characteristics include adjustable and fixed frequency operation, multi-topology support, and an error amplifier. The device is designed to be interchangeable with UC2842 and UC3842 series controllers.
