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).
