Recommended test circuit
Generally recommended capacitance: C1: 47-100μF; C2, C3: 10-22μF.
All DC/DC converters of this series are tested according to the recommended test circuit shown in the figure below before leaving the factory.
If it is required to further reduce the input and output ripple, the input and output external capacitors C1, C2, C3 can be increased or selected in series with capacitors with a small equivalent impedance, but the capacitance cannot be greater than the maximum capacitive load of the product.
EMC solution-recommended circuit
Recommended parameters:
FUSE: Connect the corresponding fuse according to customer needs
MOV varistor: 14D330K
LDM1/common mode inductance: 2mH
E1, E2 electrolytic capacitors: 470μF/50V
C0, C1 ceramic capacitors: 1μF/50V
LDM2 differential mode inductor: 4.7 μH
CY1 safety Y2 capacitor: 1nF/250Vac
Output filter peripheral recommended circuit
Note:
1. C2 and C3 use high frequency and low resistance electrolytic capacitors, and the total capacity should not exceed the maximum capacitive load marked in the manual, otherwise the module will not start normally.
2. For capacitive load, a minimum load of 3% must be guaranteed, otherwise it will cause abnormal output of the module.
Recommended parameters:
LDM3/LDM4 inductance: 2.2μH
C2, C3 electrolytic capacitor: 100μF
C4 ceramic capacitor: 1μF/50V
Ripple & noise test: twisted pair method 20MHz bandwidth
testing method:
1. Ripple noise is connected using 12# twisted pair, the oscilloscope bandwidth is set to 20MHz, 100M bandwidth probe, and 0.1uF polypropylene capacitor and 47uF high frequency low resistance electrolytic capacitor are connected in parallel to the probe end, and the oscilloscope sampling uses Sample sampling mode .
2. Connect the power input terminal to the input power source, and connect the power output to the electronic load through the fixture board. Use a 30cm±2cm sampling line to sample directly from the power output port for testing. The power line selects the corresponding wire diameter wire with insulation according to the output current. (As shown in FIG)
Pin description:
1: -Vin input negative; 2: +Vin input positive; 3: +Vo output positive; 4: NC; 5: -Vo output negative; 6: NC
*Note: If the definition of each pin of the power module is not consistent with the selection manual, the marking on the physical label shall prevail.
