AOZ1051PI - Alpha & Omega Semiconductor
Rev. June 1 of 14 AOZ1051 PIEZBuck 3 A Synchronous Buck RegulatorGeneral DescriptionThe AOZ1051PI is a high efficiency, easy to use, 3 A synchronous buck regulator. The AOZ1051PI works from V to 18 V input voltage range, and provides up to 3 A of continuous output current with an output voltage adjustable down to V. The AOZ1051PI comes in an exposed pad SO-8 package and is rated over a -40 C to +85 C operating ambient temperature V to 18 V operating input voltage rangezSynchronous Buck: 70 m internal high-side switch and 40 m internal low-side switch (at 12 V)zUp to 95 % efficiencyzExternal soft startzOutput voltage adjustable to V z3 A continuous output currentz500 kHz PWM operationzCycle-by-cycle current limitzPre-bias start-upzShort-circuit protectionzThermal shutdownzExposed pad SO-8 packageApplicationszPoint of load DC/DC converterszLCD TVzSet top boxeszDVD and Blu-ray players/recorderszCable modems Typical ApplicationFigure 1.
