DESCRIPTION
These miniature point-of-load (POL) switching
DC/DC converters are ideal regulation and supply
elements for distributed power and intermediate
bus architectures. Fully compatible with the Dis-
tributed-power Open Standards Alliance specifi-
cation (www.dosapower.com), LSN2’s can power
CPU’s, programmable logic and mixed-voltage
systems with little heat and low noise. A typical
application uses a master isolated 12Vdc supply
and individual LSN2 converters for local 1.8 and
3.3Vdc supplies. All system isolation resides in
the central supply, leaving lower cost POL regula-
tion at the load. The LSN2’s can deliver very high
power (to 112 Watts) in a tiny area without heat
sinking or external components. They feature
quick transient response (to 25sec) and very fast
current slew rates (to 20A/sec).
