Features
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 (10.8V
to 13.2V input range) and convert it, with the highest efciency in the
smallest space, to a 1, 1.1, 1.2, 1.3, 1.5, 1.8, 2, 2.5, 3.3 or 5 Volt output
fully rated at 10 Amps.
LSN D12's are ideal point-of-use/load power processors. They typi-
cally require no external components. Their vertical-mount packages
occupy a mere 0.7 square inches (4.5 sq. cm), and reversed pin vertical
mount allows mounting to meet competitor's keep out area. Horizontal-
mount packages ("H" sufx) are only 0.34 inches (8.6mm) 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 50mVp-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 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 10 Amps at ambient
temperatures
to +68°C with 100 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.
