DESCRIPTION
The 6001 inductor has been specifically
designed for operation with the ZETEX
ZXRD1000 PWM DC-DC Controllers or the
Simplesync
TM
high efficiency converters.
The dual winding offers a unique
synchronous solution for on card conversion.
ABSOLUTE MAXIMUM RATINGS
1 Specifications typical at T
A
= 2 5 C
2 If current is flowing in both windings the maximum DC current occurs when either the inductance falls to 75% of its
nominal value or when its temperature rise reaches 40C, whichever is sooner.
3 For tape and reel packaging details refer to datasheet NDC AN002.
Operating free air temperature range
40C to 85C

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.
