MAX8529 1.5MHz, Dual, 180° Out-of-Phase, PWM Step-Down Controller With POR

The MAX8529 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. Input voltage ripple and total RMS input ripple current are reduced by synchronized 180-degree out-of-phase operation.
The switching frequency is adjustable from 600kHz to 1.5MHz with an external resistor. Alternatively, the controller CAN be synchronized to an external Clock generated to another MAX8529 or a system Clock One MAX8529 CAN be set to generate an in-phase, or 90-degree 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 degrees. These devices also feature soft-start and soft-stop.
The MAX8529 eliminates the need for current-sense resistors by utilizing the low-side MOSFET's on-resistance as a current-sense element. This protects the DC-to-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 MAX8529 includes a power-on reset output to signal the system when both outputs reach regulation.
The MAX8529 is available in a 24-pin QSOP package. An evaluation kit is available to speed designs.
