TL2843BQDRQ1 Description

Short technical summary and product information.

The TL2843BQDRQ1 from Texas Instruments is a high-performance current-mode PWM controller. It is designed to facilitate off-line or DC-to-DC fixed-frequency current-mode control schemes with minimal external components. This controller operates within a voltage range of 7.6V to 30V and supports frequencies up to 500kHz.

 

Key features include a low start-up current of less than 0.5 mA, trimmed oscillator discharge current, and current mode operation. It also incorporates automatic feed-forward compensation and latching PWM for cycle-by-cycle current limiting. The device has an internally trimmed reference with undervoltage lockout and a high-current totem-pole output with undervoltage lockout and hysteresis.

 

The TL2843BQDRQ1 is qualified for automotive applications and operates over a temperature range of -40°C to 125°C. It is available in a 14-SOIC package suitable for surface mounting.

 

This part is not recommended for new designs. Consider alternate products for new projects.
