PRODUCT OVERVIEW

Murata Power Solutions' new LSN D5 Series SIP’s

(single-in-line packages) are non-isolated DC/DC

converters that accept a 5V input (4.5V to 5.5V

input range) and deliver 1V, 1.2V, 1.5V, 1.8V, 2V,

2.5, 3.3 or 3.8V outputs at 10 Amps. LSN D5 SIP’s

take on-board 5V power and convert it, with the

highest efﬁ ciency in the smallest space, to any

lower voltage required by today’s current-hungry

DSP’s, ASIC’s and CPLD’s.

ideal for true point-of-use power processing. Ver-

tical-mount packages occupy a mere 0.7 square

inches (440 sq. mm), and they are available in

industry-standard and Tyco-compatible pinout.

Horizontal-mount packages ("H" sufﬁ x) are only

0.34 inches (8.6mm) high.

achieved with a fully synchronous, ﬁ xed-frequency

(300kHz), buck topology that also delivers: high
