TL2844BDR-8 Description

Short technical summary and product information.

The Texas Instruments TL2844BDR-8 is a current-mode Pulse Width Modulation (PWM) controller designed for off-line or DC-to-DC fixed-frequency current-mode control schemes. It features a low start-up current of less than 0.5mA and a trimmed oscillator discharge current. The device supports current mode operation up to 500kHz and includes automatic feed-forward compensation and latching PWM for cycle-by-cycle current limiting.

 

Key electrical specifications include an operating voltage range of 10V to 30V and a maximum duty cycle of 48%. The operating temperature range is -40°C to 85°C. The TL2844BDR-8 is housed in an 8-SOIC package, suitable for surface mount applications.

 

This controller is ideal for various switching regulator applications of any polarity and transformer-coupled DC/DC converters. Its internal circuitry includes an undervoltage lockout (UVLO) with hysteresis and a precision reference.
