Keywords:evaluation board  boost regulator  SEL pin 

The AAT1230 evaluation board provides a platform for test and evaluation of AnalogicTech's AAT1230 switching boost regulator. The evaluation board demonstrates the suggested size and placement of external components to achieve output voltages from 10V to 18V and up to 100mA output load. The external components are selected for small size to suit portable applications, while the layout has been optimised to achieve high efficiency and low output noise with the TSOPJW-12 package. The AAT1230 operates across an input voltage range from 2.7V to 5.5V.

The AAT1230 evaluation board provides a single 18V output or 10V output at 100mA maximum output current. The desired output is determined by the logic level of the SEL pin, which is set by the JP2 jumper setting. Connecting SEL (JP2) to logic high (Vin) sets the output voltage to 18V while logic low (GND) sets the output voltage to 10V. This document provides details on the operation and testing of the AAT1230 evaluation board. Modification of the resistor divider network (R1, R2, R3) allows outputs from 10V to 18V and up to 100mA.
