UC2844AN Description

Short technical summary and product information.

The Texas Instruments UC2844AN is a versatile current mode PWM controller suitable for various DC-DC converter topologies including Boost, Buck, Flyback, and Forward. It operates within a voltage range of 10V to 30V and supports frequencies up to 500kHz.

 

Key features include adjustable switching frequency, undervoltage lockout (UVLO) with 16V/10V thresholds, and a maximum duty cycle of 48%. The controller is optimized for off-line and DC-DC converters, offering features like low start-up current (<0.5mA), pulse-by-pulse current limiting, and a high-current totem pole output.

 

This component is housed in an 8-pin PDIP package, designed for through-hole mounting. Its operating temperature range is -40°C to 85°C (TA), making it suitable for a wide array of industrial and commercial applications requiring efficient power management.

 

The UC2844AN is an improved version of the UCx84x family, offering enhanced performance characteristics for controlling switched-mode power supplies.
