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

●

Mains insulation according to IEC60065 and IEC60950 safety
standards

●

Adjustable magnetising-to-leakage primary inductance ratio LP/L

L

(recommended values range is LP/LL@ 100 kHz = 2.5 ~ 4)

Mechanical and Magnetic Data

●

Pinout configuration: 16 dual-in-line pins with 35mm spacing and
5mm pitch

●

The ferrite core is a slim EE50-type, leading to a maximum
transformer height of 28mm above the PCB

●

Maximum horizontal dimensions: 51mm x 52mm
