DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'ST' corresponds to the TSSOP-20 package when ordering. Confirm AEC-Q100 qualification status is required for your application. Check moisture sensitivity levels and reflow soldering profiles against IPC/JEDEC standards. Ensure input voltage does not exceed the 16V limit during normal operation. Validate thermal performance within the specified -40°C to +125°C junction temperature range.

DC DC Switching Controllers Selection Notes

Select this controller when a high-voltage input interface and integrated power switch are needed. It is suitable for designs requiring fixed-frequency operation without external clock synchronization. Consider the 2 MHz frequency for minimizing passive component size. Verify that the load current requirements do not exceed the internal switch's 250 mA rating. Ensure compatibility with the desired topology among Boost, Cuk, Flyback, or SEPIC options.

DC DC Switching Controllers Part Context
