Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct packaging and temperature grade. Confirm RoHS compliance status through current product compliance reports. Check for any recent Product Change Notifications (PCN) regarding package or material updates. Ensure compatibility with existing board layouts and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when designing active clamp forward converters requiring integrated housekeeping power. Consider the TSSOP-38 package size and thermal dissipation capabilities for high-power density designs. Evaluate the 100 kHz to 500 kHz frequency range against electromagnetic interference constraints. Verify that the internal housekeeping controller meets the auxiliary power requirements of the primary switch gate drive circuitry.
