Typical application circuit

APPLICATION CIRCUIT

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: 14D101K

LDM1/common mode inductance: 15mH

E1, E2 electrolytic capacitors: 100μF/100V

C0, C1 ceramic capacitors: 1μF/100V

LDM2 differential mode inductor: 15 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 cannot 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:

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. Turn the power supplyThe input terminal is connected to the input power supply, and the power output is connected to the electronic load through the fixture board. The 30cm±2cm sampling line is used 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)
