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).

➀ Typical at Ta = +25°C under nominal line voltage and full-load conditions, unless noted. All models
are tested and specified with external 22µF tantalum input and output capacitors. These capacitors
are necessary to accommodate our test equipment and may not be required to achieve specified
performance in your applications. See I/O Filtering and Noise Reduction. “Nominal” output is 3.3V
(W3 models) or 5V (D12 models)
➁ Ripple/Noise (R/N) is tested/specified over a 20MHz bandwidth and may be reduced with external
filtering. See I/O Filtering and Noise Reduction for details.
➂ These devices have no minimum-load requirements and will regulate under no-load conditions. Regula-
tion specifications describe the output-voltage deviation as the line voltage or load is varied from its
nominal/midpoint value to either extreme.
➃ Nominal line voltage, no-load/full-load conditions.
➄ V
IN must be ≥0.5V greater than VOUT.
➅ LSN2-TXX-D12 efficiencies are shown at 5V
OUT.
➆ These are not complete model numbers. Please refer to the Part Number Structure when ordering.
