DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade and 'ST' denotes the TSSOP-20 package configuration. Confirm AEC-Q100 automotive qualification status through official Microchip documentation. Ensure compatibility with required input voltage ranges and topology constraints before integration into final designs.

DC DC Switching Controllers Selection Notes

Select this component when a high-frequency current-mode controller with an integrated switch is required for non-isolated or isolated topologies. Consider the 2 MHz switching frequency for smaller passive component sizes. Evaluate the 250 mA output limit against load requirements. Verify thermal performance within the specified operating temperature range for the target application environment.
