This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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 components for space-critical applications.

Operation to 100% duty cycle permits the lowest possible dropout voltage.
