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.
