General Description
The AOZ1281 is a high efficiency, simple to use, 1.8 A
buck regulator flexible enough to be optimized for a
variety of applications. The AOZ1281 works from a 3 V to
26 V input voltage range, and provides up to 1.8 A of
continuous output current. The output voltage is
adjustable down to 0.8 V. The fixed switching frequency
of 1.5 MHz PWM operation reduces inductor size.
