LSN2 Series
Non-isolated, DOSA-SIP, 6/10/16A Selectable-Output DC/DC Converters
FEATURES
■ User-selectable outputs: 0.75-5V
(D12 models) or 0.75-3.3V (W3 models)
■ 6, 10 or 16A maximum output current
■ Double lead free to RoHS standards
■ Selectable phased start-up sequencing
and tracking
■ Wide range VIN 8.3-14V or 2.4-5.5V
■ Up to 52 Watts total output power
■ Very high efficiency up to 95%
■ Starts up into pre-biased load
■ Fast settling, high di/dt IOUT slew rate
DESCRIPTION
These miniature point-of-load (POL) switching
DC/DC converters are ideal regulation and supply
elements for distributed power and intermedi-
ate bus architectures. Fully compatible with
the Distributed-power Open Standards Alliance
specification (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 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 with-
out heat sinking or external components. They
feature quick transient response (to 25μsec) and
very fast current slew rates (to 20A/μsec).
