To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 6A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used.

To turn the power module on and off, the user must supply a switch (open collector or equivalent) to control the voltage (Von/off) between the ON/OFF terminal and the VIN(-) terminal.

At the point of current-limit inception, the unit enters hiccup mode. If the unit is not configured with auto–restart, then it will latch off following the over current condition. The module can be restarted by cycling the dc input power or by toggling the remote on/off signal. If the unit is configured with the auto- restart option (4), it will remain in the hiccup mode as long as the overcurrent condition exists; it operates normally, once the output current is brought back into its specified range.

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-9592A. This procedure is then repeated for a different airflow or ambient temperature until a family of module output derating curves is obtained. Figure 12.

The combination of the output voltage adjustment and the output voltage initial tolerance must not exceed the allowable trim range of 80% to 110% of the nominal output voltage as measured between the Vout+ and Vout- pins. The power modules have a fixed current-limit set point. Therefore, as the output voltage is adjusted down, the available output power is reduced.
