... General Description The AOZ1010 is a high efficiency, simple to use, 2A buck regulator. The AOZ1010 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 AOZ1010 comes in an SO-8 package and is rated over a -40°C to +85°C ambient temperature range. ...

... Input Capacitor The input capacitor (C in Figure 1), must be connected 1 to the V pin and PGND pin of the AOZ1010 to maintain IN steady input voltage and filter out the pulsing input current. A small decoupling capacitor (C usually 1µF, should be connected to the V AGND pin for stable operation of the AOZ1010. 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 AOZ1010, 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 ...

... The second loop starts from the inductor, to the output capacitors and load, to the PGND pin of the AOZ1010, and to the LX pins of the AZO1010. Current flows in the second loop when the low side diode is on. In PCB layout, minimizing the two loops area reduces the noise of this circuit and improves effi ...

... Please see the thermal de-rating curves for the maximum load current of the AOZ1010 under different ambient temperatures. The thermal performance of the AOZ1010 is strongly affected by the PCB layout. Extra care should be taken by users during the design process to ensure that the IC will operate under the recommended environmental conditions ...
