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
