The 6-DSBGA package (1.2×0.8 mm) makes this a fit for space-constrained point-of-load designs in portable, battery-powered, and 5 V POL applications.
The 4 MHz switching frequency lets you use a small inductor, often in the 0.47 µH to 1.0 µH range, which keeps the total solution footprint tight.
The output voltage is set by an external resistor divider connected to the feedback pin. The reference voltage is 0.6 V — the output equals 0.6 V × (1 + R1/R2). The datasheet provides the recommended resistor values for common output voltages.
