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.
