Overview
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 Applications  High reliable DC/DC converters  High performance LCD TV  High performance cable modems Typical Application VIN CIN 10µF VIN BST EN EN AOZ6662DI LX COMP RC VCC GND FB CC C4 1µF CBST L1 (min) 2.
