Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A low power DC-DC converter, comprising: a converter stage coupled to an input node; the converter stage having a low side switch and a rectifier switch which is coupled to an output node for providing a load current to a load; the DC-DC converter further comprising a peak current detector for sensing a current at the low side switch and a zero current detector for sensing a current at the rectifier switch; wherein the DC-DC converter is configur…
