LSM-16A D12 Models
Features
Non-Isolated, 12VIN, 0.75-5VOUT
16 Amp DC/DC’s in SMT Packages
Figure 1. Simplied Schematic
LSM Series D12 SMT's (surface-mount 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. LSM D12 DC/
DC's accept a 12V input (10V to 14V input range) and convert it, with the highest
efciency in the smallest space, to a 0.75, 1, 1.2, 1.5, 1.8, 2, 2.5, 3.3 or 5 Volt output
fully rated at 16 Amps.
LSM D12'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.
The LSM's best-in-class power density is achieved with a fully synchronous,
xed-frequency, buck topology that also delivers: high efciency (95% for 5VOUT
models), low noise (50mVp-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 LSM’s feature output overcurrent detection, continuous
short-circuit protection, over-temperature protection, a remote on/off control pin
(pull low to disable), an output-voltage trim function, and a sense pin. High efciency
enables the LSM D12's to deliver rated output currents of 16 Amps at ambient tem-
peratures to +65°C with 100 lfm air ow.
If your new system boards call for multiple 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 LSM D12 SMT's will save you money.
