DC/DC CONVERTERS 36-100W High Efficiency DC/DC Converters
• Ultra-high efficiency topology, 91% at 3.3V,
88% typical at 1.8V
• Industry standard footprint
• Wide baseplate temperature, -40°C to +100°C
• 90% to 110% output trim
• No minimum load
• Overvoltage protection
• Remote on/off
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 to 75VDC and are available in output
voltages of 12V, 5V, 3.3V, 2.5V, 1.8V, 1.5V and 1.2V. 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
