DESCRIPTION
These miniature point-of-load (POL) switching
DC/DCs are an ideal regulation and supply ele-
ment for mixed voltage systems. The converter
is fully compatible with the Distributed-power
Open Standards Alliance specication
(www.dosapower.com). LSN2-T/30-D12 can
power CPU’s, programmable logic and mixed
voltage systems with little heat and low noise.
A typical application uses a master isolated
12V DC supply and the LSN2-T/30-D12 con-
verter for local 1.8V and 3.3V DC supplies.
All system isolation resides in the central
supply, leaving lower cost POL regulation
right at the load. Unlike linear regulators, the
LSN2-T/30-D12 can deliver very high power
(up to 150W) in a tiny area with no heat sink-
ing and no external components needed. The
converter features quick transient response
(to 25μsec) and very fast current slew rates
(to 20A/μsec).
LSN2-T/30-D12 is an open-frame SIP
using advanced surface mount (SMT)
assembly and test techniques. The extraor-
dinary performance is achieved with a fully
synchronous xed-frequency buck topology
delivering high efciency, tight line/load
regulation, stable no-load operation and no
output reverse conduction.
Output voltage, selected with an
external programming resistor or DC volt-
age into the trim pin, means OEM’s can
stock one model for multiple applications.
Also included are protection for out-of-
limit voltages, currents and temperature.
Other functions: a remote On/Off control,
optional Power Good output, a phased
start-up sequence and tracking system,
and a load Sense input.
