EZBuck 5A Simple Buck Regulator

The AOZ1014 is a high efficiency, simple to use, 5A buck ● 4.5V to 16V operating input voltage range
regulator. The AOZ1014 works from a 4.5V to 16V input voltage range, and provides up to 5A of continuous output current with an output voltage adjustable down to 0.8V.
● internal PFET switch for high efficiency up to
● Internal soft start
● Output voltage adjustable to 0.8V

Not recommended for new designs. The AOZ1014 comes in SO-8 and DFN-8 packages and
is rated over a -40°C to +85°C ambient temperature range.
● 5A continuous output current ● Fixed 500kHz PWM operation ● Cycle-by-cycle current limit ● Short-circuit protection ● Thermal shutdown ● Small size SO-8 and DFN-8 packages

Pin Function

Supply voltage input. When VIN rises above the UVLO threshold the device starts up. Power ground. Electrically needs to be connected to AGND.

Reference connection for controller section. Also used as thermal connection for controller section. Electrically needs to be connected to PGND.

The FB pin is used to determine the output voltage via a resistor divider between the output and GND.

External loop compensation pin.

The enable pin is active high. Connect EN pin to VIN if not used. Do not leave the EN pin floating. PWM output connection to inductor. Thermal connection for output stage.
