Step-down, wide input buck regulators for

PRODUCT OVERVIEW

ꢀ

3V to 5V wide-input range

LSM Series W3 SMT’s (surface-mount

packages) are ideal building blocks for

emerging, on-board power-distribution

schemes in which isolated 3 to 5.5V buses

deliver power to any number of non-iso-

lated, step-down buck regulators. LSM W3

DC/DC’s accept 3 to 5.5 Volts 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, or

3.3 Volt output fully rated at 16 Amps.

LSM W3’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.

(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 LSM’s feature output

overcurrent detection, continuous short-

circuit protection, over-temperature protec-

tion, a remote on/off control pin (pull low to

disable), an output-voltage trim function,

and a sense pin. High efﬁciency enables the

LSM 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 mul-

tiple supply voltages, check out the econom-

ics of on-board 3-5.5V distributed power. If

you don’t need to pay for multiple isolation

barriers, DATEL’s non-isolated LSM W3

SMT’s will save you money.

Efﬁciencies to 95ꢀ @ 16 Amps

Noise as low as 30mVp-p

Stable no-load operation

Remote on/off control

Sense pin and output voltage trim

No derating to +65°C with no fan

EMC compliant

The LSM’s best-in-class power density is

achieved with a fully synchronous, ﬁxed-

frequency, buck topology that also delivers:

high efﬁciency (97%, 3.3V^OUT,8A), low noise
