_______________General Desc ription
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 posi-
tive input voltage between 0.8V and V
OUT
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 sup-
ply 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.
