Abstract
A multiphase DC-to-DC converter is disclosed herein, which includes at least one DC-to-DC converting module. Each DC-to-DC converting module at least includes a first output inductor, a second output inductor and a current detector. The current detector is configured for detecting currents pass through the first output inductor and second output inductor. The current detector includes a first resistance, a second resistance, a first capacitor, a second capacitor, and a third resistance. The third resistance is directly or indirectly coupled between the first capacitor and a load circuit, and directly or indirectly coupled between the second capacitor and the load circuit, such that when the first capacitor is charged, a portion of the current charging the first capacitor passes through the second capacitor.
