PRODUCT OVERVIEW
These miniature point-of-load (POL) switch-
ing DC/DC converters are ideal regulation and
supply elements for mixed voltage systems. Fully
compatible with the Distributed-power Open
Standards Alliance specification (www.dosa-
power.com), LSN2’s can power CPU’s, program-
mable logic and mixed-voltage systems with little
heat and low noise. A typical application uses a
master isolated 12 or 5Vdc supply and individual
LSN2 converters for local 1.8 and 3.3Vdc sup-
plies. All system isolation resides in the central
supply, leaving lower cost POL regulation at the
load. The LSN2’s can deliver very high power (to
52 Watts) in a tiny area without heat sinking or
external components. They feature quick transient
response (to 25µsec) and very fast current slew
rates (to 20A/µsec).
