DC-to-DC converter with high-side switch and low-side switch

摘要

In general, according to one embodiment, a DC-to-DC converter includes a high-side switch, a low-side switch, a diode, a high-side controller and a low-side controller. The low-side switch is connected in series with the high-side switch. The diode is connected in parallel with the low-side switch. The high-side controller has a detector for detecting a current of the high-side switch and controls the high-side switch to be turned on or off in accordance with an output of the detector. The low-side controller controls the low-side switch to be turned off when the high-side switch is ON and controls the low-side switch to be turned on or off in accordance with a peak value of the output of the detector when the high-side switch is OFF.
