The i7A models can be used to derive additional high-power outputs from a 24 Vdc power supply, at a lower
cost
and higher efficiency than isolated DC-DC converters. These very compact products are suited for use in
robotics, drones, medical, industrial, test, measurement and portable battery-powered equipment.
Wide operating temperature range
Efficiencies of up to 98.5 percent dramatically minimise internal losses and allow the i7A to operate in
ambient
temperatures of -40 °C to +125 °C, even with low airflow conditions. The i7A’s design provides a low output
ripple and excellent response to dynamic loads. Minimal external components are required, compared to
discrete
solutions, saving cost and printed circuit board space.
Three variants
A choice of three mechanical configurations is available, measuring just 34 mm wide and 36.8 mm in length.
The
11.5 mm high open-frame model is suitable for applications requiring a low profile. The baseplate version
can be
conduction-cooled to a cold plate and is 12.7 mm high.
Models with an integral heatsink, which are for
convection or forced air cooling, are 24.9 mm high.
Trimmable output voltage
The i7A standard features include output voltage adjustment, + remote sense, remote on-off (positive or
negative
logic available), input under-voltage, over-current and over-temperature protection. Evaluation boards are
available.
All models have safety certification to the IEC/UL/CSA/EN 62368-1 standards, with CE marking to the Low
Voltage
and RoHS Directives.
