Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix (e.g., NOPB) against the manufacturer's current datasheet to confirm RoHS compliance and pinout compatibility. Confirm availability status as components may be obsolete. Ensure thermal management solutions match the PowerTSSOP package specifications for the intended load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck regulator is needed for inputs between 8 V and 30 V. Consider the 1.25 A current limit and 750 kHz frequency for filter design. Evaluate the 14-PowerTSSOP package for thermal dissipation needs relative to the application's ambient temperature and airflow constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2695 series belongs to Texas Instruments' family of high-voltage switching regulators. These devices are engineered for applications requiring robust performance from elevated input voltages. The MHX variant specifically denotes the tape-and-reel packaging format within the PowerTSSOP footprint, facilitating automated assembly processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible alternatives in the LM269x series. Verify if newer revisions offer improved efficiency or extended temperature ranges. Ensure any substitute maintains the 30 V maximum input rating and 1.25 A output capability.
