The values suggested are as shown in Table 1. If additional filtering is required, the capacitance may be increased, or expanded to an LC network as shown in Figure 1. - Minimum loading The converter needs a minimum of 10% loading to maintain output regulation. Operation under no-load conditions will not cause immediate damages but may reduce reliability, and cause performance not to meet specifications. - Regulation With a semi-regulated design, the converter's output voltage varies with load current and will change proportionally to the input voltage. If regulated output is needed, an external regulator can be used as shown in Figure 2. TABLE 1 Input Voltage 3.3, 5 V 12 V 15 V 24 V External Input Capacitance 4.7 F 2.2 F 2.2 F 1.0 F - Protection The converter has minimal protection against input overvoltage or output over-load, and may be permanently damaged if exposed to these conditions. An input clamping device can be used for input voltage limiting. An input fuse or an output fuse also be used to protect against over-loading. - Dual outputs used as a single output The +Vout and -Vout can be used to obtain a single output that is the sum of the two outputs. In this case, the COM pin - Output filtering An output capacitor is needed to meet output ripple requirements as shown in Table 2.Output capacitance may be increased for additional filtering, but should not exeed 10F or expanded to an LC network as in Figure 1. shouldn't be used. - External Regulator An external 3-terminal regulator can be connected to the output of the converter to achieve full regulation. Make sure the converter's output voltage provides sufficient head room for the regulator. An additional benefit is that the built-in protection features in the regulator, such as OCP, OTP, etc, will protect the converter also. In a complimentory supply, a negative output regulator must be used to achieve the negative regulated output.
