AOZ1210-EVA
EZBuck™ 2A Simple Buck Regulator
Evaluation Board Note
General Description
The AOZ1210 evaluation board is a fully assembled and
tested circuit board built with the AOZ1210 buck regulator
IC. It outputs a preset or adjustable voltage at up to 2A of
continuous current. The evaluation board requires an
input voltage from 4.5V to 27V. The output voltage is
preset and can be adjusted.
The AOZ1210-EVA circuit has features like current limit,
short circuit protection, input under voltage lock out,
internal soft start and thermal shut down. The current
mode control and integrated internal MOSFET minimize
component count, board area and total cost.
The AOZ1210 comes in an SO-8 package and is rated
over a -40°C to +85°C ambient temperature range.
