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%
