Typical Applications

Single output

Notes on using:

 The selection of inductance values &ZeroWidthSpace;&ZeroWidthSpace;and the frequency of the "LC" filtering network should be staggered from the DC/DC frequency to avoid mutual interference. And choose a suitable filter capacitor. If the capacitor is too large, it may cause startup problems. For each output, the recommended capacitive load value is shown in (Table 1).

Recommended capacitive load values &ZeroWidthSpace;&ZeroWidthSpace;(Table 1)

For applications where the actual output power is less than 0.5W, it is recommended not to connect external capacitors

②Overload protection

Under normal operating conditions, the product output circuit has no protection function for overload conditions. The simplest way is to connect a self-recovery fuse in series at the input, or add a circuit breaker to the circuit.

③ Input overvoltage protection circuit

The simplest device for input overvoltage protection is to connect a linear regulator with overheating protection in series at its input .

④This  product cannot be used in parallel and does not support hot plugging.
