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 Distributed-power Open Standards Alliance
specification (www.dosapower.com), LSN2’s can
power CPU’s, programmable logic and mixedvoltage 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 supplies. 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).
Continuous short circuit protection
