LOW POWER DC-DC CONVERTER AND METHOD OF OPERATING THE SAME |
摘要 |
A low power DC-DC converter includes a converter stage coupled to an input node, and having a low side switch and a rectifier switch. A peak current detector senses a current at the low side switch and a zero current detector senses a current at the rectifier switch. It is configured to set the low side switch to a non-conductive state and the rectifier switch to a conductive state if the peak current detector detects a predetermined peak current. It is configured to set the rectifier switch to a non-conductive state if the zero current detector detects zero current at the rectifier switch. A time interval between subsequent current peaks is triggered by a charge comparator receiving an average current fed to the low side and rectifier switches from the input node and a reference current coupled to the charge comparator by a reference current source.
