CUI Inc │ SERIES: VIESD1-SIP │ DESCRIPTION: DC-DC CONVERTER date 02/18/2015 │ page 4 of 5 APPLICATION NOTES 1. Filtering To get an extreme low ripple, an “LC” fi ltering network may be connected to the input and output ends of the DC/DC converter, which may produce a more signifi cant fi ltering effect. It should also be noted that the inductance and the frequency of the “LC” filtering network should be staggered with the DC/DC frequency to avoid mutual interference see (see Figure 1). Figure 1 Vin GND L L C DC DC C L C +Vo 0V -Vo In some circuits which are sensitive to noise and ripple, a fi ltering capacitor may be added to the DC/DC output end and input end to reduce the noise and ripple. However, the capacitance of the output fi lter capacitor must proper. If the capacitance is too big, a startup problem might arise. For every channel of output, providing the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor refer to the external capacitor table (see Tables 1 and 2). Table 1 Input Voltage (Vdc) External Input Capacitance (µF) 5V 4.7 12 V 2.2 24 V 1.0 Table 2 Vout (Vdc) External Output Capacitance (µF) ±5 V 4.7 ±9 V 2.2 ±12 V 1.0 ±15 V 0.47 2. Overload protection Under normal operating conditions, the output circuit of these products has no protection against over-current. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. When the environment temperature is higher than 71°C, the product output power should be less then 60% of the rated power. 3. No parallel connection or plug and play Use dual output simultaneously, forbid opening output pin(0V) to use as single output. Note: All specifications measured at 25°C, humidity <75%, nominal input voltage, and full load unless otherwise noted. cui.com For more information, please visit the product page.
