% Increase in Output Voltage, ∆ (%)

The value of Vref can be found in the Electrical Data section of this data sheet. The maximum power available from the power module is fixed. As the output voltage is trimmed up, the maximum output current must be decreased to maintain the maximum rated power of the module. It is also desirable to slightly increase the input voltage while trimming up the output with heavy load current.

As the output voltage is trimmed up, the output over-voltage protection set point is not adjusted. Trimming the output voltage too high may cause the output over voltage protection circuit to be triggered.

Remote Sense: The power modules feature remote sense to compensate for the effect of output distribution drops. The output voltage sense range defines the maximum voltage allowed between the output power terminals and output sense terminals, and it is found on the electrical data page for the power module of interest. If the remote sense feature is not being used, the Sense(+) pin should be connected to the Vo(+) pin and the Sense (-) pin should be connected to the Vo(-) pin.

The output voltage at the Vo(+) and Vo(-) terminals can be increased by either the remote sense or the output voltage adjustment feature. The maximum voltage increase allowed is the larger of the remote sense range or the output voltage adjustment range; it is not the sum of both.

As the output voltage increases due to the use of the remote sense, the maximum load current must be decreased for the module to remain below its maximum power rating.

EMC Considerations: TDK Innoveta power modules are designed for use in a wide variety of systems and applications. With the help of external EMI filters and careful layout, it is possible to meet CISPR 22 class A or B requirement. For assistance with designing for EMC compliance, please contact TDK Innoveta technical support.

Input Impedance: The source impedance of the power feeding the DC/DC converter module will interact with the DC/DC converter. To minimize the interaction, one or more 220uF to 470uF/100V input electrolytic capacitors should be present if the source inductance is greater than 4uH.

Reliability:

The power modules are designed using TDK Innoveta’s stringent design guidelines for component derating, product qualification, and design reviews. Early failures are screened out by both burn-in and an automated final test. The MTBF is calculated to be greater than 2.5M hours at
