MAX1858A Datasheet (Maxim) - Dual 180 Out-of-Phase Buck Controllers with Sequencing/Prebias Startup and POR

MAX1858A, Dual 180 Out-of-Phase Buck Controllers with Sequencing/Prebias Startup and POR

The MAX1858A/MAX1875A/MAX1876A dual, synchronized, step-down controllers generate two outputs from input supplies ranging from 4.5V to 23V.

Each output is adjustable from sub-1V to 18V and supports loads of 10A or higher.

Input voltage ripple and total RMS input ripple current are reduced by synchro

MAX1858A Features

* first-on/last-off power sequencing and soft-stop. The MAX1858A/MAX1875A/MAX1876A eliminate the need for current-sense resistors by utilizing the low-side MOSFET’s on-resistance as a current-sense element. This protects the DC-DC components from damage during output-overload conditions or output shor
