MAX710 - 3.3V/5V or Adjustable / Step-Up/Down DC-DC Converters

General Description

The MAX710/MAX711 integrate a step-up DC-DC converter 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.

AVAILABLE EVALUATION KIT AVAILABLE MAX710/MAX711 3.3V/5V or Adjustable, Step-Up/Down DC-DC Converters _______________General Description The MAX710/MAX711 integrate a step-up DC-DC converter 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 (ISHDN = 0.2µA). Standby control turns off only the step-up converter and leaves the low-power linear regulator active (IQ = 7µA). The MAX710 has a preset 3.
