The AAT1210 is a general purpose high power DC/DC boost (step-up) converter with an input voltage range from 2.7 to 5.5V. The output voltage can be set from VIN +0.5V to 18V. The ultra-small solution size and high operating efficiency makes the AAT1210 the ideal solution for battery powered and consumer applications.

The step-up converter operates at frequencies up to 2MHz, enabling ultra-small external filtering components. Hysteretic current mode control provides excellent transient response with no external compensation, achieving stability across a wide operating range with minimal design effort.

The AAT1210 true load disconnect feature extends battery life by isolating the load from the power source when the EN/SET pin is pulled low ensuring zero volts output during the disable state. This feature eliminates the external boost converter leakage path; standby quiescient current <1µA is achieved without an external switching device.

A fixed output voltage is set using two external resistors. Alternatively, the output may be adjusted dynamically across a 2.0x range. The output can toggle between two preset voltages using the

SEL logic pin or across any of 16 programmed levels using AnalogicTech's Simple Serial Control™ (S2Cwire™) interface.
