Working principle

The SI9105DN02-T1-E3 is a dual-inductor Buck converter, which is popular for providing a steady voltage output from an unregulated voltage source such as a battery or a wall adapter. A Buck converter consists of 3 main components – an inductor, a capacitor and a switch. The switch is opened and closed at a regular interval. When the switch is closed, energy is stored in the inductor. When the switch is opened, the stored energy is transferred to the output capacitor, which results in a steady voltage across the output terminals.
