Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and thermal pad configuration. Ensure that any ordering suffixes do not alter functional specifications unless explicitly stated in the datasheet. Confirm RoHS compliance status through verified environmental declarations prior to procurement integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a wide input voltage range up to 36 V with moderate output current capabilities. The integrated power MOSFET reduces external component count compared to discrete solutions. Consider the 130 kHz switching frequency when designing filter components for EMI-sensitive environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP2493 series of step-down converters designed for general-purpose power management. It shares architectural similarities with other MPS buck regulators but is distinguished by its specific 2 A current rating and 36 V input limit. The series targets cost-sensitive designs requiring reliable regulation without complex external control loops.
