Features

* detect a fault, the controller shuts down. A voltage-regulator power-OK (PWRGD) output indicates the output is in regulation. A clock enable (CLKEN) output provides proper system startup sequencing. Additionally, the MAX8771 has a phase-good (PHASEGD) output, and the MAX8770/MAX8772 includes true di

Applications

* either bucking down the battery directly to create the core voltage, or else bucking down the +5V system supply. The singlestage conversion method allows this device to directly step down high-voltage batteries for the highest possible efficiency. Alternatively, 2-stage conversion (stepping down th
