MAX1744EUB/V+

The MAX1744EUB/V+ is a automotive high voltage, step down DC to DC controller in 10 pin µMAX package. The step down DC to DC controller capable of handling up to 36V inputs. It use a current-limited control scheme for excellent light and full-load efficiency while the 330KHz (max) switching frequency permits small external components for space-critical applications. Operation to 100% duty cycle permits the lowest possible dropout voltage. The MAX1744 contains an internal feedback network that provides a pin-selectable output voltage of either 3.3V or 5V. Typical applications include automotive electronics, telecom systems, wall-cube-powered devices, industrial control systems and Firewire®/IEEE® 1394.
