Data Sheet

Description

The HBT17ZGHH DC-DC Converter operates over an input voltage range of 33Vdc to 75Vdc and provid es 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 i s 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.
