APPLICATION NOTE

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, and that this product should never be operated

under no 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, or use our company

’s products with

a lower rated output power.

TRL Terminal

When open or

high impedance, the converter work well; When this pin is

‘high’; the

converter

shutdown;

It

should

be

note

that

the

input

current

should

between

5-10mA,exceeding the maximum 20mA will cause permanence damage to the converter. The

value of R can be derived as follows:

Recommended Circuit

If you want to further decrease the input/output

ripple, an

“LC” filtering network may be connected

to the input and output ends of the DC/DC

converter, see (Figure 1).

However, the capacitance of the output 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 greatest capacitance of

its filter capacitor sees (Table 1). General:

Cout:100uF
