Abstract:
1. A DC/DC converter for converting an input voltage to a predetermined output voltage at an output node, comprising: a first switch for receiving said input voltage; an inductor for coupling said first switch to said output node of said DC/DC converter such that said output voltage being generated at said output node; a first voltage divider coupled to said output node for generating a divided voltage; a second voltage divider coupled between said first switch and ground; a capacitor coupled between said first voltage divider and said second voltage divider, the capacitor being capable of measuring a current passing through said inductor by sensing a voltage across said capacitor, and a controller coupled to said first switch for enabling and disenabling said first switch such that power being discontinuously provided from said input voltage to the inductor and said output voltage being adjusted to a predetermined level.
