PRODUCT OVERVIEW

LSN D12 DC/DC's accept a 12V input (10-14V input

range) and convert it, with the highest efﬁciency in

the smallest space, to a 0.75 to 5 Volt output fully

rated at 10 Amps. The output is user-adjustable by

trim resistor or adjustment voltage.

LSN D12's are ideal point-of-use/load power

processors. They typically require no external

components. Their vertical-mount packages

occupy a mere 0.7 square inches (4.5 sq. cm),

and reversed pin vertical mount allows mounting

to meet competitor's keep out area. Horizontal-

mount packages ("H" sufﬁx) are only 0.35 inches

(8.89mm) high.

The LSN's best-in-class power density is achieved

with a fully synchronous, ﬁxed-frequency, buck

topology that also delivers: high efﬁciency (96.5%

www.murata-ps.com

For devices with the sense-pin removed ("B" sufﬁx), the feedback path is through the +Output pin and not the +Sense pin.

High power density building blocks ideal for on-board

power-distribution schemes in which isolated 12V buses

deliver power to any number of non-isolated, step-down

buck regulators.

line/load regulation, quick step response (50μsec),

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, thermal shutdown and a

sense pin. High efﬁciency enables, the LSN D12's to

deliver rated output currents of 10 Amps at ambient

temperatures to +85°C with natural convection.

If your new system boards call for three or more

supply voltages, check out the economics of

on-board 12V distributed power. If you don't need

to pay for multiple isolation barriers, Datel non-

isolated LSN D12 SIP's will save you money.
