DC-DC преобразователи интегральные MAX1745AUB+

DC/DC контроллер , понижающий, 4.5В до 36В, 1 выход, 330кГц, µMAX-10

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
