PRODUCT OVERVIEW  
nꢀ  
¼-brick size, through hole or SMT  
The LQN D12 Series of non-isolated quarter bricks  
high efficiency (95% for 5Vo u t 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 efficiency enables the LQN  
D12s to deliver rated output currents of 50 Amps  
at high ambient temperatures and minimal  
air flow.  
nꢀ  
1% setpoint accuracy  
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

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.
