LM2594MX-3.3 Description

Short technical summary and product information.

The LM2594MX-3.3 from Texas Instruments is a 500mA, step-down (buck) switching voltage regulator. It provides a fixed 3.3V output voltage and operates with an input voltage range from 4.5V to 40V. The device features a fixed 150kHz internal oscillator, offering a low component count design that requires only four external components.

 

Key electrical characteristics include a maximum output current of 500mA and a typical quiescent current of 5mA. The operating temperature range is -40°C to 125°C (TJ). The regulator is designed with built-in thermal shutdown and current-limit protection for enhanced reliability.

 

This component is available in an 8-pin SOIC surface-mount package, measuring 4.9mm x 6mm. Its design is suitable for various power management applications where a stable, regulated DC voltage is required from a higher input voltage source. The SIMPLE SWITCHER architecture simplifies design and reduces board space.

 

The LM2594MX-3.3 is RoHS3 compliant and has an MSL 1 rating. It is designed for efficient power conversion with a maximum duty cycle of 100%.
