MAX1744 Description
The MAX1744/MAX1745 are step-down DC-DC controllers capable of handling up to 36V inputs. These parts use a proprietary current-limited control scheme for excellent light- and full-load efficiency, while their 330kHz (max) switching frequency permits small external ponents for space-critical applications. Operation to 100% duty cycle permits the lowest possible dropout voltage.
