The DC/DC converter stage requires an external N-channel FET, which gives the designer flexibility to choose the Rds(on) and gate charge that match the output voltage and current, but adds two or three BOM lines and a bit of board area. If you are replacing a PD controller that had the switch inside, this part shifts that component to the layout — check the SOIC-20 footprint against your existing board before committing. ## Active, current, and available through independent distribution The MCZ34670EGR2 is listed as Active with no last-time-buy or phase-out notice. This part can be specified into the BOM without lifecycle risk.","metaTitle":"MCZ34670EGR2 PoE PD Controller, 12.95 W, 802.3af, 20-SOIC","metaDescription":"MCZ34670EGR2 is an 802.3af-compliant PoE PD controller with DC/DC control, 12.95 W max, 60 V supply, 4.5 mA supply current, -40 to 85°C, 20-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Controller (PD), DC/DC","Package":"Bulk","Standards":"802.3af (PoE)","Power - Max":"12.95 W","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","Auxiliary Sense":"No","lifecycle_stage":"eol_hot","Current - Supply":"4.5mA","Voltage - Supply":"60V (Max)","Internal Switch(s)":"No","Number of Channels":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.83","stockQuantity":0,"priceTiers":[{"qty":79,"price":"$3.83000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1be7008ccd5e5c97cadbee655dc2122b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MCZ34670EGR2 support the 802.3af PoE standard?","answer":"Yes, the MCZ34670EGR2 is compliant with the 802.3af PoE standard, covering the PD-side detection, classification, and power-good handshake."},{"question":"Can MCZ34670EGR2 be used in 48V systems?","answer":"Yes.
