PRODUCT OVERVIEW

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 efﬁ 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.

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”

sufﬁ x) are only 0.37 inches (9.4mm) high.

quency, buck topology that also delivers: high

efﬁ ciency (96% for 5VOUT models), low noise

(±0.1%/±0.25% max.), quick step response

output reverse conduction.
