Procurement Notes
Verify the specific suffix against official Analog Devices documentation to ensure correct package type and temperature grade. Confirm RoHS compliance status through the manufacturer's latest release notes. Cross-reference the part number with authorized distributors to validate authenticity. Check for any recent product change notices that may affect specifications or availability. Ensure the ordering information matches the required lead time and packaging format.
Selection Notes
Select this controller when a forward topology is required for isolated DC-DC conversion. Consider the 100 kHz to 500 kHz switching frequency range for design flexibility. Evaluate the 200 mA output current limit against load requirements. Verify compatibility with the SSOP-16 package constraints. Assess the need for operation at temperatures up to 125°C for environmental resilience.
