LSN-16A D12 Models
Features
Non-Isolated, 12VIN, 0.75-5VOUT
16 Amp DC/DC’s in SIP Packages
Figure 1. Simplied Schematic
LSN Series D12 SIP's (single-in-line packages) are ideal building blocks for
emerging, on-board power-distribution schemes in which isolated 12V buses deliver
power to any number of non-isolated, step-down buck regulators. LSN D12 DC/DC's
accept a 12V input (10V to 14V input range) and convert it, with the highest ef-
ciency in the smallest space, to a 0.75, 1, 1.2, 1.5, 1.8, 2.5, 3.3 or 5 Volt output fully
rated at 16 Amps.
LSN D12's are ideal point-of-use/load power processors. They typically require
no external components. Their vertical-mount packages occupy a mere 0.72 square
inches (4.6 sq. cm), and reversed pin vertical mount allows mounting to meet
competitor's keep out area. Horizontal-mount packages ("H" sufx) are only 0.37
inches (9.4mm) high.
The LSN's best-in-class power density is achieved with a fully synchronous,
xed-frequency, buck topology that also delivers: high efciency (96% for 5VOUT
models), low noise (30 to 55mVp-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 overcurrent detection, continuous
short-circuit protection, an output-voltage trim function, a remote on/off control pin
(pull high to disable), thermal shutdown and a sense pin. High efciency enables
the LSN D12's to deliver rated output currents of 16 Amps at ambient temperatures
to +68°C with 200 lfm air ow.
If your new system boards call for three or more supply voltages, check out the
economics of on-board 12V distributed power. If you don't need to pay for multiple
isolation barriers, DATEL's non-isolated LSN D12 SIP's will save you money.
