Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'MHX' confirms the tape-and-reel packaging format and the '/NOPB' indicates lead-free compliance. Confirm the manufacturer is Texas Instruments to avoid counterfeit components. Check the datasheet revision date to ensure compatibility with your design specifications. Ensure the operating temperature range meets your environmental requirements. Validate pinout compatibility if replacing existing designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed standard 5V or 12V rails but remain below 30V. It is suitable for applications requiring moderate output currents around 1.25A. Consider the PowerTSSOP package for surface-mount assembly needs. Evaluate the fixed switching frequency against EMI constraints in your system. Compare efficiency curves at your specific load and input voltage conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM269x family of high-voltage buck regulators. It shares architectural similarities with other members like the LM2695SDX but differs in package type and thermal performance. The family targets industrial and automotive markets where reliability and wide input ranges are critical. It complements lower-voltage regulators by handling higher potential differences efficiently.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2695MH/NOPB for leaded versions or LM2695SDX/NOPB for WSON packages. Verify pin-to-pin compatibility and thermal characteristics before substitution. Ensure the replacement maintains the same 30V input rating and 1.25A output capability. Check for any changes in switching frequency or control loop stability.
