General-purpose DC-DC conversion modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB confirms lead-free and RoHS compliance per manufacturer specifications. Confirm the 'S' designation indicates the surface-mount TO-263 package variant. Ensure the '-15' suffix matches the required fixed 15V output specification for the target circuit design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15V output is required from a variable or lower input source. The 3A current rating suits moderate power applications. Consider the TO-263 package for thermal management needs compared to smaller form factors. Verify input voltage does not exceed the 40V maximum absolute rating.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2577 family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2576 (buck) and LM2575 (older buck) series but utilizes a boost topology. The device integrates the controller and power switch into a single IC for simplified design.
