General Information
The M20W power module is a member of
Bourns industrial temperature range, dual-
output family. The system designer obtains
flexibility in choosing 5 V and 3.3 V
components based on the ability of the
module to supply either voltage over a wide
power range to the load. The output
voltages are tightly and independently
regulated, thus eliminating the common
problem of cross regulation errors between
the outputs. The M20W is capable of 20 W
combined output power. The module is
designed with Bourns’ resonant primary
and synchronous secondary topology for
enhanced reliability and high efficiency,
allowing high-temperature operation.
