Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component status before procurement as the datasheet explicitly states 'NRND' (Not Recommended for New Designs) and recommends the MP2499A for future projects. Confirm availability through authorized distributors, as stock levels may be limited due to the end-of-life status. Ensure the specific suffix matches required packaging and temperature ratings.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component only if existing designs require the specific MP2499 topology or USB integration. For new developments, evaluate the MP2499A as the primary alternative per manufacturer guidance. Consider the QFN-26 thermal performance and ensure the PCB layout supports the selected switching frequency configuration for optimal stability.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP2496/MP2499 series of synchronous buck converters from Monolithic Power Systems.
