TL3844BDR Description

Short technical summary and product information.

The TL3844BDR from Texas Instruments is a high-performance current-mode PWM controller designed for off-line or DC-to-DC fixed-frequency current-mode control schemes. It supports boost, flyback, and forward topologies, offering flexibility in power supply designs.

 

Key electrical specifications include an operating voltage range of 10V to 30V, a maximum duty cycle of 48%, and an adjustable switching frequency up to 500kHz. The device features frequency control and is suitable for applications requiring a single positive output.

 

This controller is available in a 14-SOIC package, designed for surface mounting. The operating temperature range is from 0°C to 70°C. Internally implemented circuits include an undervoltage lockout (UVLO) and a precision reference trimmed for accuracy. The output stage is designed to source or sink high-peak current, suitable for driving N-channel MOSFETs.
