The AAT1102 is a step-up DC-DC converter with a 1.6A,  0.23Ω internal switch. Equipped with an external compensation pin, this device offers users flexibility in determining loop dynamics and adjusting operating frequency.  AAT1102 also allows the use of small, low equivalent resistance (ESR) ceramic output capacitors, and it’s capable of converting a standard input of 3.3V to multiple outputs of 8V, V 8 − , and 23V.  Furthermore, filtering and loop performance are facilitated and enhanced by a high switching frequency of either 640 kHz or1.3MHz.  
The AAT1102’s versatility comes with a power-smart design.  A Soft-start programmed with an external capacitor that sets the input current ramp rate, reduces the current consumption to A 1 . 0 µ   in shutdown mode. When operating, a mere 2.6V input yields an impressive output voltage as high as 12V.      
High switching frequency and economical design allow AAT1102 to be less than 1.1mm high. Its compact 8-pin MSOP package and superior performance makes it an ideal part for biasing TFT displays.
