AOZ6662DI
EZBuckTM 2A Synchronous Buck Regulator
General Description
The AOZ6662DI is a high efficiency, easy to use, 2A synchronous buck regulator at high switching frequency for small form factor solution. The AOZ6662DI works from 4.5V to 18V input
voltage range, and provides up to 2A of continuous output current with an output
voltage adjustable down to 0.6V.
The AOZ6662DI comes in a DFN 3mm x 3mm package and is rated over a -40°C to +85°C operating ambient temperature range.
Features
4.5V to 18V operating input
voltage range Synchronous Buck: 145mΩ internal high-side switch
and 90mΩ Internal low-side switch Up to 95% efficiency Pulse Energy Mode for light load efficiency. (Vin=12V,
Vo=5V, 87%@10mA) Output
voltage adjustable to 0.6V 2A continuous output current 750kHz PWM operation External compensation Internal Soft Start Cycle-by-cycle current limit Pre-bias start-up Short-circuit protection Thermal shutdown
