Alpha & Omega Semiconductor AOZ1094DI

Description

The AOZ1094DI evaluation board is a fully assembled and tested circuit board built with the AOZ1094DI buck regulator IC. It outputs an adjustable voltage up to 5A of continuous current. The evaluation board requires an input voltage from 4.5 to 16V. The output voltage is preset at 3.3V and can be adjusted down to 0.8V.

The AOZ1094DI-EVB circuit has features like current limit, short circuit protection, input under voltage lock out, internal soft start and thermal shut down. It operates at a fixed 500 kHz switching frequency. The integrated internal MOSFET minimize component count, board area and total cost.

The AOZ1094DI-EVB demonstrates the simple buck converter design. Only one resistor value change is needed for different output voltage designs. The AOZ1094DI-EVB also supports single layer board design
