General Description

The AOZ1019 evaluation board is a fully assembled and tested circuit board built with the AOZ1019 buck regulator IC. It outputs a preset or adjustable voltage and up to 2A of continuous current. The evaluation board requires an input voltage from 4.5V to 16V. The output voltage is preset and can be adjusted from 0.8V to VINâ€“0.4V
The AOZ1019-EVA circuit features include; current limit, short circuit protection, input under voltage lock out, internal soft start and thermal shut down. It operates at a fixed 500kHz switching frequency. The current mode control and integrated internal MOSFET minimize component count, board area and total cost.
The AOZ1019 comes in an SO-8 package and is rated over a -40Â°C to +85Â°C ambient temperature range.
