Figure 1. Simplied Schematic
The LEN D12 Series of non-isolated eighth
bricks are ideal building blocks for emerg-
ing, on-board power-distribution schemes
in which isolated 12V buses deliver power
to any number of non-isolated, step-down
buck regulators. LEN D12 DC/DCs accept a
12V input (10.2V to 13.8V input range) and
convert it, with the highest efciency in the
smallest space, to a 0.8, 1, 1.2, 1.5, 1.8, 2,
2.5, or 3.3 Volt output fully rated at 28 Amps,
or 5 Volt output at 25 Amps.
LEN D12s are ideal POLPP's (point-of-use/
load power processors) and they typically re-
quire no external components. They occupy the
standard eighth-brick board space (0.9" x 2.3")
and come in either through-hole packages or
surface-mount packages with a prole of only
0.46" (0.5" including optional heat sink).
The LEN's best-in-class power density is
achieved with a fully synchronous,xed-
frequency, 2-phase buck topology that deliv-
ers extremely high efciency (95% for 5VOUT
models), low noise (25mVp-p typ.), tight
line/load regulation (±0.25% max.), quick
step response (150μsec), stable no-load
operation, and no output reverse conduction.
The fully functional LEN's feature input
over/undervoltage lockout, output overvolt-
age and overcurrent detection, continuous
short-circuit protection, overtemperature
protection, an output-voltage trim function,
a remote on/off control pin, and a sense pin.
High efciency enables the LEN D12s to
deliver rated output currents of 25 Amps at
ambient temperatures to +65°C with 200 lfm
air ow without heat sink.
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,
MPS’s non-isolated and 1∕8 brick’s will save
you money.
