MAX866ESA+

The MAX866ESA+ is a single-cell DC to DC converter in 8 pin NSOIC package. It is an ultra-small, high-efficiency, CMOS, step-up, DC to DC switching regulators for 1-cell battery-powered systems. The MAX866 accepts a positive input voltage between 0.8V and VOUT and converts it to a higher, pin-selectable output voltage of 3.3V or 5V. Typical efficiencies are greater than 80%. Typical no-load supply current is 100µA (1µA in shutdown). The MAX866 combines ultra-low quiescent supply current and high efficiency to give maximum battery life. Its high switching frequency permits the use of small, low-cost inductors and capacitors. Additionally, internal peak-current limiting protects the IC. Typical applications include pagers, remote controls, detectors, 1-cell battery-operated equipment and backup supplies.
