MAX710/MAX711
3.3V/5V or Adjustable,
Step-Up/Down DC-DC Converters
Functional Diagrams
_______________General Description
The MAX710/MAX711 integrate a step-up DC-DC con-
verter with a linear regulator to provide step-up/down
voltage conversion. They are optimized for battery
applications where the input varies above and below
the regulated output voltage. They have an input range
from +1.8V to +11V. Typical efficiency when boosting
battery inputs is 85%.
The MAX710/MAX711 can be configured for minimum
noise or optimum efficiency. Shutdown control turns off
the part completely, disconnecting the input from the
output (I SHDN = 0.2μA). Standby control turns off only
the step-up converter and leaves the low-power linear
regulator active (I Q = 7μA).
The MAX710 has a preset 3.3V or 5V output voltage.
The MAX711 has an adjustable output that can be set
from +2.7V to +5.5V with two resistors. Both devices
come in 16-pin narrow SO packages.
