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 - Regulation Table 1. If additional filtering is required, the With a semi-regulated design, the converter’s output capacitance may be increased, or expanded to an LC voltage varies with load current and will change network as shown in Figure 1. proportionally to the input voltage. If regulated output is needed, an external regulator can be used Table 1 as shown in Figure 2. Input Voltage External Input Capacitance 5V 4.7 µF 12 V 2.2 µF 15 V 2.2 µF An input clamping device can be used for input 24 V 1.0 µF voltage limiting. An input fuse or an output fuse - Protection The converter has minimal protection against input over-voltage or output over-load, and may be permanently damaged if exposed to these conditions. can also be used to protect against over-loading. - Output filtering - External Regulator An output capacitor is needed to meet output ripple An external 3-terminal regulator can be connected requirements as shown in Table 2. to the output of the converter to achieve full Output capacitance may be increased for additional regulation. Make sure the converter’s output voltage filtering, but should not exeed 10µF or expanded to provides sufficient head room for the regulator. An an LC network as in Figure 1. additional benefit is that the built-in protection features in the regulator, such as OCP, OTP, etc, will Table 2 protect the converter also.
