TL2845BDR-8 Description

Short technical summary and product information.

The TL2845BDR-8 from Texas Instruments is a 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 features include operation up to 500kHz, a wide operating voltage range of 7.6V to 30V, and a maximum duty cycle of 48%. It incorporates features such as low start-up current (<0.5mA), trimmed oscillator discharge current, and an internally trimmed reference with undervoltage lockout (UVLO). The UVLO thresholds are typically 8.4V (on) and 7.6V (off) for this series.

 

This controller is suitable for applications such as switching regulators of any polarity and transformer-coupled DC/DC converters. The device operates within an ambient temperature range of -40°C to 85°C and is housed in an 8-SOIC package suitable for surface mounting.

 

The TL2845BDR-8 offers features like automatic feed-forward compensation, latching PWM for cycle-by-cycle current limiting, and a high-current totem-pole output. It is designed to drive N-channel MOSFETs.
