AOZ1017-EVA
EZBuck 3A Simple Buck Regulator
Evaluation Board Note
General Description
The AOZ1017 evaluation board is a fully assembled and
tested circuit board built with the AOZ1017 buck regulator
IC. It outputs a preset or adjustable voltage and up to 3A
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 V
IN
–0.4V
The AOZ1017-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 AOZ1017 comes in SO-8 packages and is rated over
a -40°C to +85°C ambient temperature range.
