LM2625M

Voltage Regulators - DC DC Switching Regulators Overview

The LM2625M is a synchronous step-down DC/DC converter manufactured by National Semiconductor, now part of Texas Instruments. It integrates high-side and low-side N-channel power MOSFETs to achieve high efficiency in a compact surface-mount package. The device operates with an input voltage range supporting various single-cell battery or regulated bus supplies. Internal compensation simplifies external component selection while maintaining stability across load transients. The controller utilizes fixed-frequency pulse-width modulation for consistent performance.

Integrated synchronous rectification using internal N-channel MOSFETs
Fixed-frequency current mode control architecture
Internal frequency compensation for simplified design
Compact surface-mount packaging for space-constrained applications

Voltage Regulators - DC DC Switching Regulators Applications

Portable electronics powered by single-cell lithium-ion batteries
Point-of-load regulation for digital signal processors
Battery-powered instrumentation systems
Embedded communication modules requiring efficient voltage conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments depending on production era. Confirm the suffix indicates adjustable output configuration. Ensure the package marking aligns with the MSOP-8 physical dimensions. Cross-reference the datasheet revision date to confirm pinout compatibility with existing designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when high efficiency at moderate currents is required without external Schottky diodes. The integrated MOSFETs reduce board space compared to asynchronous alternatives. Verify that the desired output voltage falls within the adjustable range defined by the external resistor divider network. Ensure input voltage remains within the specified operational limits for stable regulation.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM262x family of synchronous buck converters. It shares architectural similarities with the LM2623 and LM2624, differing primarily in output current capabilities and thermal characteristics. The series targets applications needing reliable step-down conversion from single-cell sources.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2650M-ADJ/NOPB serves as a functional substitute within the Texas Instruments portfolio. Both devices offer synchronous step-down conversion with similar control architectures. Verify pin-to-pin compatibility and thermal performance requirements before substitution.
