Product details

Dual 6A buck in a 3.5x4.6 mm FC2QFN

The MAX20812AFH+T: Housed in a 21-PowerVFQFN (FC2QFN) package measuring 3.5 mm x 4.6 mm, it is a surface-mount part suited for space-constrained PCB layouts.

Switching frequency and output flexibility

A higher frequency shrinks the magnetics but increases FET switching loss; the 3 MHz ceiling keeps the converter out of the AM band and simplifies EMI filtering in sensitive receiver chains. Each output is independently adjustable via an external resistor divider, with a minimum reference of 0.5 V. The positive-output configuration means no negative-rail generation without an additional inverting stage. Note that the synchronous rectifier is listed as 'No' — this is an asynchronous (diode-rectified) buck. The external Schottky diode adds a component but eliminates the risk of cross-conduction and simplifies the layout for designers who prefer a discrete catch diode over an integrated FET.

Active production, RoHS3, and sourcing

RoHS3 compliant (2015/863/EU), with no exemptions flagged.

Frequently asked questions

What package does the MAX20812AFH+T use?

It is supplied in a 21-PowerVFQFN package, specifically the 21-FC2QFN (3.5 mm x 4.6 mm) footprint. This is a surface-mount, exposed-pad package designed for thermal dissipation into the PCB copper plane.
