Part Overview
Description
The MAX1730 is a regulated step-down charge pump that generates up to 50mA at fixed output voltages of 1.8V or 1.9V from an input voltage in the 2.7V to 5.5V range. It employs fractional conversion techniques to provide efficiency exceeding that of a linear regulator. The MAX1730 operates at up to 2MHz, permitting the use of small 0.22uF flying capacitors while maintaining low 75μA quiescent supply current. Proprietary soft-start circuitry prevents excessive current from being drawn from the supply during startup, making the MAX1730 compatible with higher impedance sources such as alkaline and lithium-ion cells.
