PRODUCT OVERVIEW

ꢀ

On/Off control, trim & sense functions

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 efﬁciency 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 proﬁle of only 0.4" (0.5" including heatsink).

The LQNs best-in-class power density is

high efﬁciency (95% for 5V^OUTmodels), 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 efﬁciency enables

the LQN D12s to deliver rated output currents

of 50 Amps at high ambient temperatures and

minimal air ﬂow.

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.
