... General Description The AOZ1014 is a high efficiency, simple to use, 5A buck regulator. The AOZ1014 works from a 4.5V to 16V input voltage range, and provides continuous output current with an output voltage adjustable down to 0.8V. The AOZ1014 comes in SO-8 and DFN-8 packages and is rated over a -40°C to +85°C ambient temperature range ...

... Figure 1. Component selection is explained below. Input Capacitor The input capacitor must be connected to the V PGND pin of the AOZ1014 to maintain steady input volt- age and filter out the pulsing input current. The voltage rating of input capacitor must be greater than maximum input voltage plus ripple voltage. ...

... COMP pin sets the pole-zero and is adequate for a stable high-bandwidth control loop. In the AOZ1014, FB pin and COMP pin are the inverting input and the output of internal transconductance error amplifier. A series R and C compensation network connected to COMP provides one pole and one zero ...
