APPLICATIONS

200

111

The B_(X)T-1W Series are specially

designed for applications where a group of

polar power supplies are isolated from the

input power supply in a distributed power

supply system on a circuit board.

10.8-13.2

3.3

These products apply to:

300

200

110

1) Where the voltage of the input power

supply is fixed (voltage variation ≤ ±10%);

2) Where isolation is necessary between

input and output (isolation voltage

≤1000VDC);

3) Where the regulation of the output voltage

and the output ripple noise are not

demanding.

21.6-26.4

Such as: purely digital circuits, ordinary low

frequency analog circuits, and IGBT power

device driving circuits.

Note :1.the B_XT-1W series have no 3,6,7 pin. For example B0505XT-1W.

2. B_XT-1W :UL-60950-1 pending.

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.

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).

TYPICAL CHARACTERISTICS

(Figure 1)

It should also be noted that the inductance and the

frequency of the “LC” filtering network should be

staggered with the DC/DC frequency to avoid

mutual interference. 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).

It’s not recommend to connect any external capacitor

Output Voltage Regulation and Over-voltage

Protection Circuit

The simplest device for output voltage regulation,

over-voltage and over-current protection is a linear

voltage regulator with overheat protection that is

connected to the input or output end in series

Overload Protection

Under normal operating conditions, the output

circuit of these products has no protection against

over-current and short-circuits. The simplest

method is to connect a self-recovery fuse in series

at the input end or add a circuit breaker to the

circuit.
