Abstract

A boost converter receives an input voltage and provides an output voltage and includes a power switch and a voltage control circuit configured to drive the power switch as a function of the output voltage. A voltage sensing circuit in the form of a voltage divider is coupled to sense the output voltage and provide a feedback voltage. The voltage control circuit drives the power switch. An electronic control switch is configured to selectively connect the voltage divider to sense the output voltage as a function of an enable signal generated by a timer circuit. The enable signal is pulsed such that the voltage divider is periodically connected to sense the output voltage during a first time and is disconnected from sensing during a second time.
