Note:
1. It is recommended a 0.1μF bypass capacitor is connected between VDD and the closest VSS pin of the device.
2. For ensuring power stability, a 2.2μF Capacitor must be connected between LDO_CAP pin and the closest VSS pin of
the device.
3. For ensuring power stability, a 2.2μF Capacitor must be connected between LDO_CAP pin and the closest VSS pin of
the device.

DC-DC
Typical values are at VDD = 3.3V, TA = 25°C, Vsw is connected to 4.7uH inductance and LDO_CAP is
connected to 2.2uF capacitance unless otherwise specified.
