3.3V/5V or Adjustable-Output / Single-Cell DC-DC Converters
_______________General DescriptionThe 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 VOUTand 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.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS(Circuit of Figure 2, VIN= 1.2V, ILOAD= 0mA, TA= +25°C, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:Reverse battery current is measured from the Typical Operating Circuit’sbattery input terminal to GND when the battery is
connected backwards. A reverse current of 750mA will not exceed the package dissipation limits but, if left for an extended
time (more than ten minutes), may degrade performance.

Note 2:Output current specified with circuit of Figure 2 and CoilCraft D01608-334 inductor for test purposes only. More (or less)
output current can be supplied with other coil types depending on inductance value and coil resistance. See Typical Operating
Characteristicsfor other coil types. Output voltage and output current are guaranteed over this VIN operating range once the
device has started up. Actual VIN start-up voltage depends on load current.
Note 3:Output voltage specifications over temperature are guaranteed by design to limits that are 6 sigma from either side of the mean.
Note 4:Current measured into OUT. VOUTis forced to 3.47V to maintain LX off when measuring device current.
