DESCRIPTION:

The ATI2202EV1 is the evaluation board for the ATI2202 Step-Down DC/DC Converter. It has a wide supply range from 4.75V to 18V and can output up to 2A current continuously. It features a synchronous rectification with integrated high and low side power MOSFETs to achieve high efficiency. The output voltage of this board can be set to from 0.923V to 0.9×Vin by adjusting a potentiometer. The current mode control and integrated power MOSFETs minimize component counts, board area, and solution cost. Fault condition protections include cycle-by-cycle current limiting, thermal shutdown, and under-voltage lockout. Programmable soft-start reduces turn-on stress imposed to the system power supply. The small SOP-8 package comes with a heat sink pad which allows transferring the converter IC's heat to the heat sink formed by the PCB.
