TL2845D Description

Short technical summary and product information.

The TL2845D from Texas Instruments is an integrated circuit designed for implementing fixed-frequency current-mode control schemes in off-line and DC-to-DC converters. This device features a voltage range of 7.6V to 30V and can operate at frequencies up to 500kHz, with a maximum duty cycle of 48%.

 

Key electrical features include adjustable switching frequency, current limiting, and an error amplifier. The controller supports multiple topologies such as Boost, Flyback, and Forward, and it is not a synchronous rectifier. It operates within a temperature range of -40°C to 85°C.

 

The TL2845D is available in a 14-SOIC surface mount package. Its design is optimized for efficiency and performance in power management applications, offering features like pulse-by-pulse current limiting and undervoltage lockout with hysteresis. It is designed to be interchangeable with UC2842 and UC3842 series controllers.
