The MAX5037's internal voltage regulator allows operation from a 5 V, 12 V, or 24 V power bus. The 4A integrated MOSFET drivers and 2 W package power dissipation allow over 60 A output current. Multiple DC/DC controller modules can be paralleled to achieve higher output currents in units of 60 A per module. The MAX5037 includes an on-board 5-bit D/A converter. The device includes overvoltage protection. Additionally, the MAX5037 includes thermal shutdown and a phase failure detector to warn the microprocessor of impending power-supply failure in the event that one of the phases fails. Other features include external frequency synchronization, phase-shifted clock output, true differential remote output-voltage sensing, and power-good output. The MAX5037 operates over the 㫀°C to +85°C temperature range and is available in a 44-pin MQFP or 44-pin QFN package.
