Description
The HBT17ZGHH DC-DC Converter operates over an input voltage range of 33Vdc to 75Vdc and provides
three isolated output voltages. The 5V output can provide a full 60W (12 Amperes) of output power and each
12V output can provide up to 30W (2.5 Amperes) of output power. The input is fully isolated from each
output and each output is isolated from one another. The isolation of each output provides flexible output
configurations and separate output returns, which are important in preventing cross-interference between
different loads in system applications. The module has a typical full load efficiency of 88%.
The two-board construction optimizes thermal performance. Power devices are connected to an Integrated
Metal Substrate base plate to minimize thermal impedance and a separate control board is physically
isolated from the hotter IMS board. This approach allows for lower average component temperatures on the
control board and increases the overall reliability. The comprehensive standard feature set includes remote
on/off, and output trim.
