AOZ6763DI 3A 1.25MHz Synchronous EZBuckTM Regulator General Description Features The AOZ6763DI is a high efficiency, easy to use, 3A
synchronous buck regulator at high switching frequency
for small form factor solution. The AOZ6763DI works
from 4.5V to 18V input voltage range, and provides up to
3A of continuous output current with an output voltage
adjustable down to 0.6V. 4.5V to 18V operating input voltage range The AOZ6763DI comes in a DFN 3mm x 3mm package
and is rated over a -40°C to +85°C operating ambient
temperature range. Pulse Energy Mode for light load efficiency (Vin=12V, Synchronous Buck: 145mΩ internal high-side switch and 80mΩ Internal low-side switch Up to 95% efficiency 30ns controllable minimum on-time enabling this part can work at Vo=0.9V with 12V power rail
Vo=5V, 86%@10mA) Output voltage adjustable to 0.6V 3A continuous output current Fixed frequency 1.25MHz PWM operation External compensation for flexible LC design Internal Soft Start Cycle-by-cycle current limit Pre-bias start-up Short-circuit protection Thermal shutdown Applications High performance wireless AP/router High reliable DC/DC converters High performance LCD TV High performance cable modems Typical Application
