adjustable output voltage from 0.9 V to 3.3 V. It uses synchronous
rectification to increase efficiency and reduce external part count.
The device also has a built-in 3.0 MHz (nominal) oscillator which
reduces component size by allowing a small inductor and capacitors.
Automatic switching PWM/PFM mode offers improved system
