Page 10 Figure 16. Circuit diagram showing connection of RTUNE and CTUNE to tune the control loop of the module. Table 1 shows the recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 8000 F that might be needed for an application to meet output ripple and noise requirements. Table 1. General recommended values of of RTUNE and CTUNE for Vout=28V and various external ceramic capacitor combinations.

Over Temperature Protection The JRCW016A0R module provides a non-latching over temperature protection. A temperature sensor monitors the operating temperature of the converter. If the reference temperature, TREF 1, (see Figure 17) exceeds a threshold of 115 ºC (typical), the converter will shut down and disable the output. When the base plate temperature has decreased by approximately 20 ºC the converter will automatically restart. The module can be restarted by cycling the dc input power for at least one second or by toggling the remote on/off signal for at least one second. Thermal Considerations The power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat-dissipating components inside the unit are thermally coupled to the case. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the case temperature. Peak temperature (TREF) occurs at the position indicated in Figure 17. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel, using automated thermo-couple instrumentation to monitor key component temperatures: FETs, diodes, control ICs, magnetic cores, ceramic capacitors, opto-isolators, and module pwb conductors, while controlling the ambient airflow rate and temperature. For a given airflow and ambient temperature, the module output power is increased, until one (or more) of the components reaches its maximum derated operating temperature, as defined in IPC-9592. This procedure is then repeated for a different airflow or ambient temperature until a family of module output derating curves is obtained. Heat-dissipating components inside the unit are thermally coupled to the case. Heat is removed by conduction, convection, and radiation to the surrounding environment. For reliable operation this temperature should not exceed 100ºC at either TREF 1 or TREF 2 for applications using forced convection airflow or cold plate applications. The output power of the module should not exceed the rated power for the module as listed in the ordering Information table. Although the maximum TREF temperature of the power modules is discussed above, you can limit this temperature to a lower value for extremely high reliability. Figure 17.
