Description

The MAX866 and MAX867 are ultra-small, high-efficiency, CMOS, step-up, DC-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. The MAX867 adjustable version accepts 0.8V to 6.0V input voltages and generates a higher adjustable output voltage in the 2.7V to 6.0V range. Typical efficiencies are greater than 80%. Typical no-load supply current is 100µA (1µA in shutdown). The MAX866/MAX867 combine 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.
