Overview
MAX1744/MAX1745 19-1776; Rev 4; 8/09 EVAALVUAAILTAIOBNLEKIT High-Voltage, Step-Down DC-DC Controllers in µMAX 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.
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.
