Applications

* with a minimal number of external components.
It operates from a 4.5-V to 18-V input supply voltage, and supports output voltages as low as 0.8 V and as high as 90% of the input voltage.
Both high-side and low-side MOSFETs are integrated to provide fully synchronous conversion with higher efficiency
