AAT1210

The AAT1210 is a 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 total solution is less than 1mm in height. High operating efficiency makes the AAT1210 the ideal solution for battery powered and consumer applications.

The step-up converter AAT1210 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 operatingrange 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 and achieves standby quiescient current <1A 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. Optionally, the output can be dynamically set to any one of 16 programmed levels using AnalogicTech's patented Simple Serial Control™ (S2Cwire™) interface.

The AAT1210 is available in a Pb-free, thermallyenhanced 16-pin 3x4mm TDFN low-profile package and is rated over the -40°C to +85°C temperature range.
