AOZ1212AI

The AOZ1212 is a high efficiency, simple to use, 3A buck regulator flexible enough to be optimized for a variety of applications. The AOZ1212 works from a 4.5V to 27V input voltage range, and provides up to 3A of continuous output current on each buck regulator output. The output voltage is adjustable down to 0.8V. The AOZ1212 comes in an SO - 8 or DFN - 8 package and is rated over a -40°C to +85°C ambient temperature range. The AOZ1212 is a current - mode step down regulator with integrated high side NMOS switch. It operates from a 4.5V to 27V input voltage range and supplies up to 3A of load current. The duty cycle can be adjusted from 6% to 85% allowing a wide range of output voltages. Features include enable control, Power - On Reset, input under voltage lockout, fixed internal soft - start and thermal shut down. The AOZ1212 is available in an SO - 8 or DFN - 8 package.
