SLOT SMT 100 W
Series 2642 – Resonant-Type Power Supply Switch-Mode
Transformer
Applications
This transformer is mainly intended to be used as a Resonant Switch-Mode Transformer for
low-end 22” LCD TV sets with mains insulation. The most suitable circuit topology for this
transformer is a half-bridge, quasi-resonant converter using Phillips ZVS controller TEA1610.
The common range of operation for this switch-mode transformer is from 50-200 kHz.
Features
●
Magnetic circuit of this transformer consists of EE-type ferrite
cores having a squared central leg where the windings and
the air gap are placed
●
Maximum primary power: 100 W @ 100 kHz.
●
Slot technology, Lizt wire is recommended for proximity and
skin effects reduction
●
Mains insulation according to IEC60065 and IEC60950 safety
standards
●
Recommended magnetising-to-leakage primary inductance ratio

SLOT SMT 200 W
Series 2652 – Resonant-type Power Supply Switch-Mode
Transformer
Applications
This transformer is mainly intended to be used as a Resonant Switch-Mode Transformer
for high-end 30” to 42” LCD TV sets with mains insulation. The most suitable circuit
topology for this transformer is a half-bridge, quasi-resonant converter using ON
Semiconductor’s ZVS controller MC34067. The common range of operation for this
Switch-Mode Transformer is from 50-150 kHz.
Features
●
Magnetic circuit of this transformer consists of two (asymmetrical)
E-type ferrite cores having a rectangular central leg where the
windings and the air gap are placed
●
Maximum primary power: 200 W @ 100 kHz
●
Slot technology, Lizt wire recommended for proximity and skin
effects reduction
