Overview
MAX1730 19-1618; Rev 0; 4/00 50mA Regulated Step-Down Charge Pump for 1.
8V or 1.
9V Logic General Description The MAX1730 regulated step-down charge pump 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.
Specifically designed to provide high-efficiency logic supplies in applications that demand a compact design, the MAX1730 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.
22µF flying capacitors while maintaining low 75µA quiescent supply current.
Proprietary softstart 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.
The MAX1730 is available in a space-saving 10-pin µMAX package that is only 1.
09mm high and occupies one-half the area of an 8-pin SO.
Applications Low-Volta...
