Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (NOPB) confirms lead-free status and RoHS compliance if required by your manufacturing standards. Confirm the package type matches your PCB footprint design. Check current availability as this component may have limited stock or obsolescence status depending on the distributor. Ensure the fixed or adjustable variant matches your circuit design requirements before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require two isolated or non-isolated regulated outputs from a single input source. Consider the 24-TSSOP package constraints regarding thermal dissipation and board space. Evaluate the need for external compensation components based on the chosen switching frequency. Compare against single-channel regulators if only one output is strictly necessary to reduce cost and complexity.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2717 family of dual synchronous buck converters. It serves as a lead-free, RoHS-compliant version of the standard LM2717 series. The NOPB suffix indicates the absence of lead-based materials, aligning with environmental regulations. It is designed to replace older National Semiconductor equivalents in modern power management designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2717MT is the direct equivalent part number. Verify pin compatibility and electrical specifications match exactly. Check for updated revisions or newer generations from Texas Instruments that may offer improved efficiency or smaller packages.
