Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM3578AMX

LM3578AMX

Voltage Regulators - DC DC Switching Regulators Overview

The LM3578AMX is a switching regulator IC manufactured by Texas Instruments, housed in an 8-SOIC package. It supports Buck, Boost, and Buck-Boost topologies with a wide input voltage range of 2V to 40V. The device delivers a maximum output current of 750mA and operates at a fixed switching frequency of 20kHz. It functions with positive or negative outputs and includes internal compensation for stable regulation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Supports versatile Buck, Boost, and Buck-Boost converter configurations
Wide input voltage capability from 2V to 40V
Internal frequency compensation simplifies external component selection

Voltage Regulators - DC DC Switching Regulators Applications

Industrial control systems requiring isolated or non-isolated DC-DC conversion
Battery-powered equipment utilizing Buck-Boost architectures
Negative voltage generation circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'AMX' against the official datasheet to confirm it denotes the tape-and-reel packaging variant of the LM3578AM. Ensure the component matches the commercial temperature range specifications (0°C to 70°C) required for your application environment before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed low-frequency operation at 20kHz is preferred to minimize electromagnetic interference or allow for smaller passive components. It is suitable for applications requiring a single inductor solution for both step-up and step-down requirements within the specified current limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3578 family of switching regulators, originally developed by National Semiconductor and now produced by Texas Instruments. It serves as a cost-effective alternative to more complex multi-switch controllers by integrating the power switch and control logic into a single compact SOIC package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM3578AM/NOPB is the manufacturer-recommended lead-free replacement for the LM3578AM series. Verify pin compatibility and thermal performance when transitioning between these variants.
