MAX1875, MAX1876 Dual 180° Out-of-Phase PWM Step-Down Controllers With POR

The MAX1875 MAX1876 dual, synchronized, Step-down controller generates two outputs from input supplies ranging from 4.75V 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 to another MAX1875 MAX1876 or a system Clock One MAX1875 MAX1876 CAN be set to generate an in-phase, or 90 out-of-phase, Clock signal for synchronization with additional controllers. This allows two controllers to operate either as an interleaved two- or four-phase system with each output shifted by 90. These devices also feature soft-start and soft-stop.
The MAX1875 MAX1876 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 when output short-circuit faults without requiring a current-sense resistor. Adjustable foldback current limit reduces power dissipation during short-circuit conditions. The MAX1876 includes a power-on reset output to signal the system when both outputs reach regulation.
The MAX1875 MAX1876 are available in a 24-pin QSOP package. An evaluation kit is available to speed designs.
