6001
Zetex Compatible ZXRD1000 Inductor
APPLICATION NOTES
The 6001 inductor enables the basic
architecture of a non synchronous converter
to be used to generate synchronous operation
without the need for complex circuitry and
additional cost.
The 6001 generates a drive waveform that is
inverted compared to the waveform at the
main input to the inductor. This waveform can
be used to drive the synchronous switch. The
net result gives additional benefits and lowers
the overall cost.
