DESCRIPTION
The MPQ series of single output DC/DC converters provides up to 125 watts in a quarter-brick package. The MPQ series is
well suited for telecom and datacom applications where high efficiencies are required. Some features include over voltage
protection, short circuit protection, over current protection, positive or negative remote on/off, and ±10% output trim. All
models are 100% burn-in tested. This converter offers great performance and high reliability at a very competitive price.
