Dual 180° Out-of-Phase Buck Controllers with Sequencing/Prebias Startup and POR
General Description
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 synchronized 180° out-of-phase operation.
The switching frequency is adjustable from 100kHz to 600kHz with an external resistor.
Alternatively, the controller can be synchronized to an external clock generated by another MAX1858A/MAX1875A/MAX1876A or a ...
