The EXQ125 is a new ultra high efficiency, open-frame, isolated converter series in
an industry standard quarter-brick footprint that provides up to 100 Watts of output
power. The EXQ125 delivers very high output current at low voltages, and excellent
useable power density for today’s high end applications. The seven models in the
series feature an input voltage range of 33 Vdc to 75 Vdc and are available in output
voltages of 12 V, 5 V, 3.3 V, 2.5 V, 1.8 V, 1.5 V and 1.2 V. The output voltage on each
model is adjustable from 90% to 110% of the nominal value. The EXQ125 series
also has a remote ON/OFF capability. Overcurrent and overvoltage protection
features are included as standard. With full international safety approval including
EN60950 (TÜV Rheinland) and UL/cUL1950, the EXQ125 reduces compliance costs
and time to market.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

2The EXQ125 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
See Application Note 118.
3Recommended input fusing is a 5 A HRC 200 V rated fuse.
4This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
5Measured with no external Pi filter. Significant reduction possible with
external filter. See Application Note 118.
6Start-up into resistive load.
