In the case of a boost regulator, the arrangement of components (inductor, diode, capacitors) are a little different. In a boost regulator, higher voltage is produced when the switching FET connects/disconnects the output of the inductor to ground. In a buck regulator, the input of the inductor is switched instead. Check out this TI application report titled Working with Boost Converters for more details. | |

Clarified PMIC vs switching regulator

PMIC is more of a generic term for a chip that does more than just regulates power, usually has a management interface or some kind of monitoring built in. | |
