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/DC's
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 D12's are ideal POLPP's (point-of-use/load power processors) and they
typically require no external 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 LQN's 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 (70sec), stable no-load operation, and no output
reverse conduction.
The fully functional LQN's feature input over/undervoltage lockout, output over-
voltage and overcurrent detection, continuous short-circuit protection, overtempera-
ture protection, an output-voltage trim function, a remote on/off control pin, a sense
pin and a current share function (optional). High efciency enables the LQN D12's 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, DATEL's non-isolated LQN D12 brick's will save you money.
