TL2845BDR Description

Short technical summary and product information.

The TL2845BDR from Texas Instruments is a high-performance current-mode Pulse Width Modulation (PWM) controller IC. It is designed to facilitate the implementation of off-line or DC-to-DC fixed-frequency current-mode control schemes with minimal external components.

 

Key electrical specifications include an operating voltage range of 7.6V to 30V and a maximum duty cycle of 48%. The device supports operation at frequencies up to 500kHz, making it suitable for a wide range of power supply designs. It features a low start-up current of less than 0.5mA and internally trimmed reference voltage with undervoltage lockout.

 

This controller is ideal for switching regulators of any polarity and transformer-coupled DC/DC converters. The TL2845BDR is housed in a 14-SOIC package, designed for surface mount applications. Its operating temperature range is -40°C to 85°C, ensuring reliable performance in various environmental conditions.
