TL3844P Description

Short technical summary and product information.

The Texas Instruments TL3844P is an integrated circuit designed for fixed-frequency current-mode control schemes in 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 supports multiple topologies including Boost, Flyback, and Forward configurations. Key electrical features include frequency control for adjustable switching frequency and pulse-by-pulse current limiting. The device is designed for ease of use with a minimum number of external components.

 

The TL3844P is available in an 8-DIP (0.300", 7.62mm) package, suitable for through-hole mounting. It operates within a temperature range of 0°C to 70°C (TA).

 

This part is optimized for applications requiring efficient power conversion, offering features like automatic feed-forward compensation and enhanced load-response characteristics. It is designed to be interchangeable with UC2842 and UC3842 series controllers.
