ABSTRACT:
A DC to DC converter with voltage regulator for converting a low level voltage source to a higher level DC, comprising an oscillator circuit with a low resistance starting current path, a rectifier circuit for rectifying the oscillator output, and a regulator for providing a regulated DC output voltage of predetermined level. The oscillator embodies one or more FET devices connected to provide an extremely low DC startup resistance as well as a low cutoff voltage characteristic. With this configuration, the low startup current from the voltage source can initiate switching so that oscillation can occur.
