| AOZ3018PI EZBuck 5 A Synchronous Buck Regulator The AOZ3018 is a high efficiency, simple to use, 5 A synchronous buck regulator. The AOZ3018 operates from a V to 18 V input voltage range, and provides up to 5 A of continuous output current with an output voltage adjustable down to V. The AOZ3018 comes in an exposed pad SO-8 package and is rated over a -40 °C to +85 °C operating ambient temperature range. V to 18 V operating input voltage range 55 internal high-side switch and 19 internal low-side switch at 12 V Up to 95 % efficiency External soft start Output voltage adjustable to V 5 A continuous output current 500 kHz PWM operation Cycle-by-cycle current limit Pre-bias start-up Short-circuit protection Thermal shutdown Exposed pad SO-8 package Point of load DC/DC converters LCD TV Set top boxes DVD and Blu-ray players/recorders Cable modems C1 10µF RC CC AOZ3018 LX COMP AGND PGND L1 4.7µH R1 R2 VOUT C2, C3 22µF Figure V, 5 A Synchronous Buck Regulator, Fs = 500 kHz Page 1 of 14 Ordering Information Part Number AOZ3018PI Ambient Temperature Range -40 °C to +85 °C Package EPAD SO-8 AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.

Pin Configuration PGND 1 VIN 2 AGND 3 FB 4 PAD LX 8 LX 7 SS 6 EN 5 COMP Exposed Pad SO-8 Top View AOZ3018PI Environmental Green Product Pin Description Pin Number 1 2 Pin Name PGND VIN AGND COMP 7 8 Exposed pad SS LX Sense Pin Function Power ground. PGND needs to be electrically connected to AGND. Supply voltage input. When VIN rises above the UVLO threshold and EN is logic high, the device starts up. Analog ground. AGND is the reference point for controller section. AGND needs to be electrically connected to PGND. Feedback input. The FB pin is used to set the output voltage via a resistive voltage divider between the output and AGND. External loop compensation pin. Connect a RC network between COMP and AGND to compensate the control loop. Enable pin. Pull EN to logic high to enable the device. Pull EN to logic low to disable the device. If on/off control in not needed, connect EN to VIN and do not leave it open. Soft-start pin. 5 µA current charging current. Switching node. This pin has to be externally connected to exposed pad LX through PCB. Switching node. LX is the drain of the internal power FET. LX is used as the thermal pad of the power stage.
