Abstract
A switching voltage regulator control device, includes first and second half-bridges each comprising a switch. The first half-bridge is located between an input voltage and a reference voltage and the second half-bridge is located between an output voltage and the reference voltage. The regulator comprises a detector for detecting the error between a reference voltage representative of the output voltage and another reference voltage and an integrator for integrating said error. The control device is suitable for providing a first duty cycle for driving the switch of the first half-bridge that is proportional to the integrated error divided by the input voltage and a second duty cycle for driving the switch of the second half-bridge that is proportional to the value of the input voltage divided by the integrated error.
