Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'YWM' confirms the 20-lead SOIC package and 3.3V fixed output variant. Ensure the '-TR' designation matches the required reel packaging quantity of 1000 units. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the full part number against the latest datasheet revision to ensure pinout and electrical specifications remain unchanged.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required without external feedback resistor programming. The 2.5A current rating suits moderate load applications where space constraints favor a 20-SOIC footprint over larger packages. Consider the 200kHz frequency for balancing electromagnetic interference and passive component size. Evaluate thermal performance requirements given the junction temperature limits and package thermal resistance characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MIC2177 series of synchronous switchers. It shares architectural similarities with other variants like the MIC2177-5.0YWM but differs in output voltage configuration. The series utilizes Microchip's proprietary current-mode control technique. It competes in the general-purpose synchronous buck regulator market segment. The device represents a solution for efficient power management in portable and industrial systems.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

MIC2177-5.0YWM-TR offers identical functionality with a 5.0V fixed output instead of 3.3V. MIC2178-5.0CWM-TR provides higher current capability (5.5A) but uses different packaging and control parameters. Verify pin compatibility and thermal characteristics when substituting with these alternatives.
