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 exter
nal components for space-critical applications.
Operation to 100% duty cycle permits the lowest possible dropout voltage. The
MAX1744 contains an internal feedback network that provides a pin-selectable
output voltage of either 3.3V or 5V. The MAX1745 uses an external feedback
network to generate an adjustable output voltage between 1.25V and 18V.
The MAX1744/MAX1745 are available in a space-saving 10-pin μMAX®package.
