MAX1745AUB+

The MAX1745AUB+ is a 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 MAX1745 uses an external feedback network to generate an adjustable output voltage between 1.25V and 18V.

• Supply voltage range is 4.5V to 36V
• Operating temperature range from -40°C to 125°C
• Quiescent current is 90μA
• Shutdown current is 4μA
• Output power capability exceeds 50W
• Low dropout voltage
• Efficiency is greater than 90%
