AOZ1014-EVA EZBuck™ 5A Simple Buck Regulator Evaluation Board Note General Description Features The AOZ1014 evaluation board is a fully assembled and ● 4.5V to 16V operating input voltage range tested circuit board built with the AOZ1014 buck regulator ● Output voltage was preset to 3.3 V, adjustable to as IC. It outputs a preset or adjustable voltage at up to 5A of low as 0.8V continuous current. The evaluation board requires an ● 5A continuous output current input voltage from 4.5V to 16V. The output voltage is preset and can be adjusted from 0.8 V to VIN–0.4V ● Fixed 500kHz PWM operation ● Internal soft start The AOZ1014-EVA circuit has features like current limit, ● Cycle-by-cycle current limit short circuit protection, input under voltage lock out, internal soft start and thermal shut down. It operates at ● Short-circuit protection a fixed 500kHz switching frequency. The current mode ● Thermal shutdown control and integrated internal MOSFET minimize component count, board area and total cost. Applications ● Point of load DC/DC conversion The AOZ1014 comes in SO-8 and DFN-8 packages and is rated over a -40°C to +85°C ambient temperature ● PCIe graphics cards range. ● Set top boxes
