Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SX' indicates reel packaging when ordering. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance as per manufacturer specifications. Ensure the TO-263-7 package variant matches the target PCB footprint requirements before finalizing procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a fixed 12 V output from a 4 V to 40 V input source. The integrated flyback controller simplifies external transformer selection compared to discrete solutions. Consider the 200 kHz switching frequency for balancing component size against electromagnetic interference constraints in the target application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2588 series of SIMPLE SWITCHER regulators. It differs from the LM2587 by supporting higher output currents and utilizing a flyback topology rather than just boost. The SX suffix denotes tape and reel packaging, while the TO-263-7 package provides thermal performance suitable for high-current applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2588S-12/NOPB is a tube-packaged equivalent with identical electrical characteristics. LM2587S-12/NOPB offers similar functionality but with different packaging and potentially lower current capabilities.
