Procurement Notes
Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure that the selected variant matches the required thermal performance and pinout configuration for the target PCB layout. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and supply chain integrity before finalizing procurement orders.
Selection Notes
Select this controller when designing systems requiring flexible topology support such as step-up or step-down conversion. Consider the 4V to 60V input range suitability for varying source conditions. Evaluate the need for clock synchronization if multiple converters operate in proximity to prevent interference. Confirm that the 300kHz switching frequency aligns with the desired trade-off between component size and electromagnetic interference levels.
