DESCRIPTION

P6142 is a planar power transformer using

multilayer PCB technology. It is intended for low

profile high frequency discontinuous flyback DC-DC

converters up to 500kHz. With careful design, output

power exceeding 20W is achievable.

P6142 has split primaries that can be configured in

series or parallel for nominal 24V and 12V systems

respectively,

with

nominal

15V

output.

The

recommended input voltage range is 10V to 32V.

Additionally, an auxiliary winding is provided on the

primary side.

The contacts to the host circuit board are made

by solder connection to large plated-through

holes in the P6142 PCB, thus ensuring low

resistance connection. The ferrite is intended to

sit within a PCB cut-out, giving a height above

board of 4mm.

P6142 is lead-free (Pb-free) and suitable for

conventional and lead-free processing.
