Operation under no-load - Input filtering To reduce the reflected ripple current and minimize conditions will not cause immediate damages but EMI, especially when the converter input is more may reduce reliability, and cause performance not to than 2” away from the DC source, it is recommended meet specifications. to connect a low ESR electrolytic capacitor between Vin and Gnd. The values suggested are as shown in - Protection Table 1. If additional filtering is required, the The converter has minimal protection against input capacitance may be increased, or expanded to an LC over-voltage or output over-load, and may be network as shown in Figure 1. permanently damaged if exposed to these conditions. An input clamping device can be used for input Table 1 voltage limiting. An input fuse or an output fuse can also be used to protect against over-loading. Input Voltage External Input Capacitance 5V 4.7 µF As fixed input converters, this series can accept 12 V 2.2 µF voltages within a limited range of the nominal input. 24 V 1.0 µF - Unregulated input Otherwise the converter may not function properly or may be damaged. - Output filtering An output capacitor as shown in Table 2 may be used to reduce output ripples and noise. requirements as shown in Table 2.
