DESIGN CONSIDERATIONS
Lin(4.7µH) Cin(220µF, ESR < 1.0Ω at 100 KHz)
1) Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum output load is not less than 10% of the full load. If the
actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load.
2) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to add a
circuit breaker to the circuit.
3) Recommended Circuit
If you want to further decrease the input/output ripple, a capacitor filtering network may be connected to the input and output ends of the DC/DC
converter, see (Figure 2).
It should also be noted that the capacitance of filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every
channel of output, provided the safe and reliable operation is ensured, the recommended capacitance of its filter capacitor sees (Table 1).
