Abstract
Some embodiments include apparatuses having a switching circuit included in a buck converter; an output node; an inductor including a first portion having a first terminal coupled to the switching circuit, a second portion having a second terminal coupled to the output node, and a third terminal between the first and second portions; and a capacitor coupled to the second terminal, the second terminal to couple to a first additional capacitor, and the third terminal to couple to a second additional capacitor.
Claims21
An apparatus comprising:
- a switching circuit included in a buck converter;
- an output node;
- an inductor including a first portion having a first terminal coupled to the switching circuit, a second portion having a second terminal coupled to the output node, and a third terminal between the first portion and the second portion, the first portion directly coupled to the second portion at a contact location, and the third terminal directly coupled to the contact location without going through a turn of the inductor;
- and
- a capacitor coupled to the second terminal, the second terminal to couple to a first additional capacitor, and the third terminal to directly couple to a first plate of a second additional capacitor, the second additional capacitor including a second plate directly coupled to a ground node.
