LM25005MH/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25005MH/NOPB is a synchronous step-down switching regulator from Texas Instruments, designed for high-efficiency power conversion. It operates with an input voltage range of 7 V to 42 V and delivers up to 2.5 A of output current. The adjustable output voltage spans from 1.225 V to 40 V. Integrated features include current mode control, a programmable switching frequency between 50 kHz and 500 kHz, and a shutdown pin for power management. The device functions reliably within a junction temperature range of -40°C to +125°C and is housed in a 20-pin HTSSOP package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous buck topology integrates internal high-side and low-side MOSFETs for enhanced efficiency.

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial point-of-load regulation
• Automotive electronics power distribution
• Telecommunications infrastructure supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MH' corresponds to the tube packaging variant rather than the 'MHX' reel version. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the required thermal performance and package dimensions for your PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 42 V is required alongside moderate current capabilities. The synchronous design reduces external component count compared to non-synchronous alternatives. Consider the thermal dissipation requirements of the HTSSOP-20 package for high-duty cycle applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM25005 family of synchronous step-down regulators. It shares core architecture with variants like the LM25005MHX/NOPB, differing primarily in packaging format. The series targets applications requiring robust performance in automotive and industrial environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM25005MHX/NOPB serves as a direct functional substitute with identical electrical specifications but utilizes tape-and-reel packaging instead of tubes.
