LSM-10A D3 Models

Single Output, Non-Isolated, 3.3VIN, 0.8-2.5VOUT

10 Amp DC/DC’s in SMT Packages

Typical Unit

DATEL's LSM D3 Series for SMT (surface-mount) are non-isolated DC/DC

converters that accept a 3.3V input (3.0V to 3.6V input range) and deliver 1V, 1.2V,

1.5V, 1.8V, 2V or 2.5V outputs at 10 Amps. LSM D3 SMT's are designed to take on-

board 3.3V 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 LSM D3's miniature size makes them ideal for true point-of-use/load power

processing. They occupy a mere 0.7 square inches (4.5 cm²) and are only 0.34

inches (8.64 mm) high. The SMT package is designed for pick and place including

lead free reflow soldering, and they typically require no additional external compo-

nents.

The LSM's best-in-class power density is achieved with a fully synchronous,

fixed-frequency (300kHz), buck topology that also delivers: high efficiency (94% for

2.5V^OUTmodels), low noise (30mVp-p typ.), tight line/load regulation ( 0.1%/ 0.25%

max.), quick step response (100μsec), stable no-load operation, and no output

reverse conduction.

The fully functional LSM's feature output overcurrent detection, continuous short-

circuit and over-temperature protection, an output-voltage trim function, a remote on/

off control pin (pull low to disable), and a sense pin. High efficiency enables the LSM

D3's to deliver rated output currents of 10 Amps at ambient temperatures to +70°C

with no air flow (natural convection).

If your low-voltage, high-current requirements have made the use of inefficient

linear regulators impractical, take a look at one of DATEL's easy-to-use, low-cost

LSM SMT's (or equivalent LSN SIP's). All devices are UL/IEC/EN60950 certified and

EMC compliant. UL, CB, HALT and EMC reports are available upon request.
