Figure 1. Simplified Schematic
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 efficiency in the smallest space, to any
lower voltage required by today’s current-hungry
DSP’s, ASIC’s and CPLD’s.
The miniature size of LSN D5's makes them
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" suffix) are only
0.34 inches (8.6mm) high.
The LSN's best-in-class power density is
achieved with a fully synchronous, fixed-frequency
(300kHz), buck topology that also delivers: high
efficiency (to 95%), low noise (10mVp-p typ.), tight
line/load regulation (±0.1%/±0.25% max.), quick
step response (100sec), stable no-load operation,
and no output reverse conduction.
The fully functional LSN’s feature output over-
current detection, continuous short-circuit protec-
tion, an output-voltage trim function, a remote on/
off control pin (pull high to disable), thermal shut-
down, and a sense pin. High efficiency enables
the LSN D5's to deliver rated output currents of
10 Amps at ambient temperatures to +71°C with
no air flow (natural convection).
If your low-voltage, high-current requirements
make the use of inefficient linear regulators
impractical, take a look at one of C&D’s easy-to-
use, low-cost LSN SIP’s. All devices are UL/IEC/
EN60950-1 certified and EMC compliant. UL, CB,
HALT and EMC reports are available upon request.
Selected models are RoHS compliant.
For devices with the sense-pin removed ("B" suffix), the feedback
path is through the +Output pin and not the +Sense pin.
Values in parenthesis for 3.3V models only.
