LSN Series W3 are ideal building blocks for emerg-
ing, on-board power-distribution schemes in which
isolated 3 to 5.5V buses deliver power to any num-
ber of non-isolated, step-down buck regulators.
LSN W3 DC/DC’s accept 3 to 5.5 Volts and convert
it, with the highest ef?ciency in the smallest space,
to a 0.75, 1, 1.2, 1.5, 1.8, 2, 2.5, or 3.3 Volt output
fully rated at 16 Amps.
LSN W3’s are ideal point-of-use/load power
processors. They typically require no external com-
ponents. 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 LSN’s best-in-class power density
is achieved with a fully synchronous, fixed-
frequency, buck topology that also delivers:
high efficiency (97%, 3.3Vout, 8A), low noise
Figure 1. Simpli?ed Schematic
(30mVp-p typ.), tight line/load regulation
(±0.1%/±0.25% max.), quick step response
(30μsec), stable no-load operation, and no
output reverse conduction.
The fully functional LSN’s feature output over-
current detection, continuous short-circuit protec-
tion, over-temperature protection, a remote on/off
control pin (pull low to disable), an output-voltage
trim function, and a sense pin. High ef?ciency en-
ables the LSN W3’s to deliver rated output currents
of 16 Amps at ambient temperatures to +65°C
with natural convection.
If your new system boards call for multiple sup-
ply voltages, check out the economics of on-board
3-5.5V distributed power. If you don’t need to pay
for multiple isolation barriers, DATEL’s non-isolated
LSN W3 SMT’s will save you money.
