Switching Converter
First Claim
1. Switching converter having a switching transistor, a first inductance and a first diode being arranged as a step-down converter for producing a first rectified output voltage from an input voltage, wherein said switching transistor is coupled with an input terminal to said input voltage via a second inductance, and a second diode is coupled to a tap being arranged between said second inductance and said switching transistor for producing a second rectified output voltage.

Abstract
The switching converter contains a switching transistor, a first inductance and a first diode, which are connected so as to form a step-down converter for the purpose of producing a first rectified output voltage from an input voltage. The switching transistor is connected on the input side to the input voltage via a second inductance, and a second diode is coupled to a tap being arranged between the second inductance and the switching transistor for the purpose of producing a second rectified output voltage. The second rectified output voltage is in this case unregulated, but can be used in particular as a supply voltage for a television tuner.
