Figure 1. Simplied Schematic
Only one phase of three shown.
Typical unit
Typical topology is shown.
The LQN D12 Series of non-isolated quarter bricks
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. LQN 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, 3.3
or 5 Volt output fully rated at 45-50 Amps.
LQN D12s are ideal POLPPs (point-of-use/load
power processors) and they typically require no ex-
ternal components. They occupy the standard quarter
brick board space (1.45" x 2.3") and come in either
through-hole packages or surface-mount packages
with a prole of only 0.4" (0.5" including heatsink).
The LQNs best-in-class power density is
achieved with a fully synchronous, xed-frequency,
3-phase buck topology that delivers extremely
high efciency (95% for 5VOUT models), low noise
(20mVp-p typ.), tight line/load regulation (±0.25%
max.), quick step response (70μsec), stable no-
load operation, and no output reverse conduction.
The fully functional LQN's feature input over/
undervoltage lockout, output overvoltage and
overcurrent detection, continuous short-circuit
protection, overtemperature protection, an
output-voltage trim function, a remote on/off
control pin, and sense pin. High efciency enables
the LQN D12s to deliver rated output currents
of 50 Amps at high ambient temperatures and
minimal 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, MPS's non-
isolated LQN D12 brick's will save you money.
