Product Summary

The MAX756CSA is a CMOS step-up DC-DC switching regulator for small, low input voltage or battery-powered systems. The MAX756CSA accepts a positive input voltage down to 0.7V and converts it to a higher pin-selectable output voltage of 3.3V or 5V. Typical full-load efficiencies for the MAX756CSA are greater than 87%. The applications of the MAX756CSA include 3.3V to 5V Step-Up Conversion, Palmtop Computers, Portable Data-Collection Equipment, Personal Data Communicators/Computers, Medical Instrumentation and 2-Cell & 3-Cell Battery-Operated Equipment Glucose Meters.
