LSN Series D12 SIP's (single-in-line pack-
ages) are ideal building blocks for emerging,
on-board power-distribution schemes in
which isolated 12V buses deliver power to
any number of non-isolated, step-down buck
regulators. LSN D12 DC/DC's accept a 12V
input (10V to 14V input range) and convert
it, with the highest ef?ciency in the smallest
space, to a 0.75, 1, 1.2, 1.5, 1.8, 2.5, 3.3 or
5 Volt output fully rated at 16 Amps.
LSN D12's are ideal point-of-use/load
power processors. They typically require no
external components. Their vertical-mount
packages occupy a mere 0.72 square inches
(4.6 sq. cm), and reversed pin vertical mount
allows mounting to meet competitor’s keep
out area. Horizontal-mount packages (“H”
suf?x) are only 0.37 inches (9.4mm) high.
The LSN's best-in-class power density is
achieved with a fully synchronous, ?xed-fre-
quency, buck topology that also delivers: high
ef?ciency (96% for 5VOUT models), low noise
(30 to 55mVp-p typ.), tight line/load regulation
(±0.1%/±0.25% max.), quick step response
(100μsec), stable no-load operation, and no
output reverse conduction.
The fully functional LSN’s feature output
overcurrent detection, continuous short-circuit
protection, an output-voltage trim function, a
remote on/off control pin (pull high to disable),
thermal shutdown and a sense pin. High
ef?ciency enables the LSN D12s to deliver
rated output currents of 16 Amps at ambient
temperatures to +68°C with 200 lfm air ?ow.
If your new system boards call for three or
more supply voltages, check out the econom-
ics of on-board 12V distributed power. If you
don’t need to pay for multiple isolation barri-
ers, DATEL's non-isolated LSN D12 SIP's will
save you money.
