MAX1744EUB/V+, DC/DC контроллер, понижающий, 4.5В до 36В питание, 100% коэффициент заполнения, 330кГц, µMAX-10

Полупроводники - Микросхемы\Микросхемы Управления Питанием\DC - DC Устройства Управления Питанием\DC - DC КонтроллерыThe MAX1744EUB/V+ from Maxim Integrated Products 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. • Supply voltage range is 4.5V to 36V, high-voltage operation (up to 36V IN)• Operating temperature range from -40°C to 85°C• Quiescent current is 90µA• Shutdown current is 4µA• Output power capability exceeds 50W• Low dropout voltage• Efficiency is greater than 90%• Automotive AEC-Q100 qualified
