PRODUCT OVERVIEW
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 effi 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.
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.
is achieved with a fully synchronous, fixed-
frequency, buck topology that also delivers:
high efficiency (97%, 3.3Vout, 8A), low noise
LSN W3’s are ideal point-of-use/load power

... See Typical Performance Curves. Remote Sense LSN W3 SMT Series DC/DC converters offer an output sense function on pin 3. The sense function enables point-of-use regulation for overcoming moderate IR drops in conductors and/or cabling.

... If the output current exceeds it maximum rating by typically 50% (24 Amps the output voltage drops to less than 98 original value, the LSN W3’s internal overcurrent-detection circuitry immediately turns off the converter, which then goes into a "hiccup" mode. While hiccupping, the converter will continuously attempt to restart itself, go into overcurrent, and then shut down ...
