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.","metaTitle":"MAX20812AFH+T Dual Buck Regulator, 6A, 21-FC2QFN","metaDescription":"Active-production dual 6A step-down buck regulator from Analog Devices. 2.7V-16V input, adjustable output to 5.8V, 500kHz-3MHz switching. 21-PowerVFQFN.
