TL3842BDR-8 Description

Short technical summary and product information.

The TL3842BDR-8 from Texas Instruments is a high-performance current-mode 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 specifications include an operating voltage range of 10V to 30V and a maximum switching frequency of 500kHz. The device features a low start-up current of less than 0.5mA and a trimmed oscillator discharge current. It operates within a temperature range of 0°C to 70°C.

 

This controller supports boost, flyback, and forward topologies and offers features such as frequency control, an error amplifier, and a latching PWM for cycle-by-cycle current limiting. The output stage is a high-current totem-pole design suitable for driving N-channel MOSFETs.

 

The TL3842BDR-8 is available in an 8-SOIC package, designed for surface mount applications. Its compact size and robust feature set make it suitable for various power supply designs.
