DCCin Lin DC Load Oscilloscope Current Probe Lin(4.7µH) Cin(220 µF, ESR < 1.0Ω at 100 KHz) DESIGN CONSIDERATIONS 1) Requirement for output load To ensure this module can operate efficiently and reliably, the minimum output load could not be less than 10% of the full load. If the actual output power is very small, please connect a resistor to the output in parallel to increase the load. 2) Overload Protection Under normal operating conditions, the output circuit of these products have not overload protection. The simplest method is to add a breaker circuit in the circuit. 3) Recommended circuit If you want to further decrease the input/output ripple, an capacitor filtering network may be connected to the input and output ends of the DC/DC converter, refer to (Figure 3). It should also be noted that the capacitance of the capacitor must be proper. If the capacitance is too large, a startup problem might arise.For ensuring every channel of output can provide a safe and reliable operation , the recommended capacitance of the capacitor refer to (Table 1). Vin GND +Vo DC Cin DC Cout (Figure 3) EXTERNAL CAPACITOR TABLE (Table 1) Vin (VDC) Cin (µF) Vo (VDC) Cout (µF) 24 1 23/27 0.47 It’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output. 4) Output Voltage Regulation and Over-voltage Protection Circuit The simplest device for output voltage regulation, over-voltage and over-current protection is a linear regulator with overheat protection which is connected to the input or output in series (Figure 4)and an capacitor filtering network.the recommended capacitance of the capacitor refer to Table 1, linear regulator based on the actual voltage and current to make a reasonable selection. Vin GND +Vo DC DC REG REG (Figure 4) 5) It is not recommended to increase the output power capability by connecting two or more converters in parallel. The product is not hot-swappable Note: 1. Operation under minimum load will not damage the converter; However, they may not meet all specifications. 2. Max. Capacitive Load is tested at nominal input voltage and full load. 3. Unless otherwise noted, All specifications are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load. 4. In this datasheet, all test methods are based on our corporate standards. 5. All characteristics are for listed models, and non-standard models may perform differently.Please contact our technical support for more detail. 6.
