PRODUCT OVERVIEW

ꢀ

Step-down buck regulators for new

distributed 12V power architectures

LSM Series D12 SMTs (surface-mount pack-

ages) are ideal building blocks for emerging,

on-board power-distribution schemes in which

isolated 12V buses deliver power to any num-

ber of non-isolated, step-down buck regulators.

LSM D12 DC/DC’s accept a 12V input (10V to

14V input range) and convert it, with the highest

efﬁciency in the smallest space, to a 0.75, 1,

1.2, 1.5, 1.8, 2, 2.5, 3.3 or 5 Volt output fully

rated at 16 Amps.

LSM D12’s are ideal point-of-use/load power

processors. They typically require no external

components. Their surface-mount packages

occupy a mere 1.3" x 0.53" (33.0 x 13.5mm),

and are only 0.34 inches (8.6mm) high.

The LSM’s best-in-class power density

noise (50mVp-p typ.), tight line/load regulation

( 0.1ꢀ/ 0.25ꢀ max.), quick step response

(100μsec), stable no-load operation, and no

output reverse conduction.

The fully functional LSM’s feature output

overcurrent detection, continuous short-circuit

protection, over-temperature protection, a

remote on/off control pin (pull low to disable),

an output-voltage trim function, and a sense

pin. High efﬁciency enables the LSM D12’s to

deliver rated output currents of 16 Amps at

ambient temperatures to +65°C with 100 lfm

air ﬂow.

If your new system boards call for multiple

supply voltages, check out the economics of

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

need to pay for multiple isolation barriers,

Murata Power Solutions’ non-isolated LSM D12

SMTs will save you money.
