LM2575MX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575MX-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER power converter, functioning as a monolithic integrated circuit step-down DC/DC regulator. It provides a fixed 5.0V output with a maximum load current of 1A. The device operates from an input voltage range up to 40V and utilizes a fixed 52kHz internal oscillator for efficient energy transfer. Packaged in the SO-8 surface-mount format, it integrates a 1A switch and includes built-in thermal shutdown and current limiting features for robust protection.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS adherence according to the manufacturer's latest documentation. Confirm the SO-8 package variant matches your PCB footprint requirements. Ensure the fixed 5.0V output specification aligns with your system voltage needs before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a reliable 1A buck converter solution is required in a small surface-mount footprint. It is suitable for applications needing a fixed 5V rail derived from higher voltage sources up to 40V. Consider its thermal performance characteristics relative to your expected ambient temperatures and board copper area for adequate heat dissipation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of SIMPLE SWITCHER regulators, known for their ease of use and minimal external component count. The MX suffix denotes the SO-8 surface-mount package, distinguishing it from through-hole variants like the TO-220 or TO-263 packages found in other family members.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible alternatives within the same family include LM2575S-5.0/NOPB (TO-263) and LM2575T-5.0/NOPB (TO-220). For different output voltages, check LM2575MX-ADJ/NOPB for adjustable configurations.
