The TL2843BD-8 from Texas Instruments is a high-performance current-mode Pulse Width Modulation (PWM) controller. 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 operating frequency of up to 500kHz. The device features a low start-up current of less than 0.5mA and a trimmed oscillator discharge current. It supports various topologies including Boost, Flyback, and Forward configurations.
The controller operates within a temperature range of -40°C to 85°C. It is available in an 8-SOIC package suitable for surface mounting.
This controller is ideal for applications requiring efficient power conversion, such as switching regulators of any polarity and transformer-coupled DC/DC converters.
