This product should never be operated under no load conditions. If the actual output power is very low you should increase the load by connecting a resistor with the proper resistance at the output end in parallel. No parallel connection or plug and play. - Overload Protection Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. - Output Voltage Regulation and Over-voltage Protection Circuit The simplest device for output voltage regulation, over-voltage and over-current protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure 2). Figure 2 +Vin -Vin REG +Vout DC DC Com -Vout - Recommended Circuit If you want to further decrease the input/output ripple, an “LC” filtering network may be connected to the input and output ends of the dc-dc converter, see (Figure 1). +Vin REG +Vout Com DC DC -Vin REG -Vout Figure 1 L L +Vin C +Vout C DC DC -Vin L Com C Reflow Profile Peak Temperature 260°C for 10 Sec. Max 220°C 200 -Vout 250 It should also be noted that the inductance and the frequency of the “LC” filtering network should mutual interference. However, the capacitance of the output filter capacitor must be proper. If the capacitance is too large, a startup problem might arise. It is not recommended to connect any external capacitor in the application field . Temperature (°C) be staggered with the dc-dc frequency to avoid 90 Sec. max (>220°C) 150 100 50 0 Time (Seconds) 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2382 phone fax
