1 / 15 page ![]() Rev. 1.1 July 2016 www.aosmd.com Page 1 of 15 AOZ6622DI EZBuckTM 2A Synchronous Buck Regulator General Description The AOZ6622DI is a high efficiency, easy to use, 2A synchronous buck regulator. The AOZ6622DI 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 0.8V. The AOZ6622DI 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: 150mΩ internal high-side switch and 90mΩ internal low-side switch Up to 95% efficiency Pulse energy mode for high light load efficiency (Vin=12V, Vo=5V, 83% @10mA) Output voltage adjustable to 0.8V Adjacent pin short protection 2A continuous output current 550kHz PWM operation Cycle-by-cycle current limit Pre-bias start-up Short-circuit protection Thermal shutdown Applications Point of load DC/DC converters LCD TV Set top boxes DVD / Blu-ray players/recorders Cable modems Typical Application AOZ6622DI VOUT CBST CIN 10µF VIN EN BST LX FB GND L1 4.7µH VIN C2,C3 22µF R1 R2 EN RT Figure 1. 3.3V 2ASynchronous Buck Regulator, Fs = 550kHz |
