Procurement Notes

Verify the specific suffix #WTRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact electrical specifications required for the target application, as suffix variations may indicate different thermal grades or package options. Cross-reference the manufacturer datasheet for any recent product change notifications that might affect pinout or functionality.

Selection Notes

Select this component when designing active clamp forward converters requiring high efficiency and wide input voltage ranges. The integrated housekeeping controller simplifies design by eliminating external bias circuitry. Consider the TSSOP-38 package for thermal management and board space constraints. Verify that the operating temperature range meets the environmental requirements of the end application.
