LM25017MRX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25017MRX/NOPB is a synchronous buck switching regulator IC from Texas Instruments, designed for high-efficiency power conversion. It features an integrated high-side and low-side MOSFETs within an 8-SO-PowerPAD package. The device supports a wide input voltage range from 7.5V to 48V and delivers an adjustable output voltage between 1.225V and 40V with a maximum output current of 650mA. Operating at a fixed switching frequency of up to 1MHz, it offers precise regulation and thermal protection. The component functions across an extended temperature range of -40°C to +125°C TJ, making it suitable for robust industrial applications requiring compact DC-DC solutions.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates high-side and low-side N-channel power MOSFETs for simplified design and enhanced efficiency in synchronous rectification.

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial point-of-load regulation
• Embedded system power distribution
• Communication equipment bias supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MRX' confirms the reel packaging configuration as documented by the manufacturer. Ensure compatibility with the 8-SO-PowerPAD footprint during PCB layout. Confirm RoHS compliance status through official datasheets prior to integration. Cross-reference the full part number against distributor catalogs to avoid substitution errors with non-NOPB variants or different package styles.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact synchronous buck solution is required for inputs up to 48V. The integrated MOSFETs reduce external component count compared to controller-only alternatives. Consider the 1MHz switching frequency for smaller passive filter sizes. Evaluate thermal performance requirements given the 650mA output capability in the SO-PowerPAD package for adequate heat dissipation in enclosed environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM25017 family of synchronous buck regulators. It shares architectural similarities with other TI PMICs but is distinct in its specific current rating and input voltage window. The MRX suffix denotes a tape-and-reel manufacturing format, differing from the MRE evaluation or bulk options. It serves as a complete power stage rather than just a control loop interface.
