Product details

PoE PD controller with DC/DC control — what it does and where it fits

It comes in a 20-SOIC (7.50 mm wide) surface-mount package, operates from -40 to 85°C, and is marked as ROHS3 compliant.

No internal switch — plan for the external MOSFET

The MCZ34670EGR2 does not include an internal switching MOSFET. 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.

Frequently asked questions

Does MCZ34670EGR2 support the 802.3af PoE standard?

Yes, the MCZ34670EGR2 is compliant with the 802.3af PoE standard, covering the PD-side detection, classification, and power-good handshake.

Can MCZ34670EGR2 be used in 48V systems?

Yes. The supply voltage is rated up to 60 V max, and 48 V nominal is well within the operating range. The part is designed for standard PoE voltage levels.

Is MCZ34670EGR2 lead-free and RoHS compliant?

Yes, the MCZ34670EGR2 is marked as ROHS3 Compliant.
