APPLICATIONS
Patent Protection
The A_M-1W & B_LM-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.
These products apply to:
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.
Such as: purely digital circuits, ordinary low frequency analog
circuits, and IGBT power device driving circuits.

OUTLINE DIMENSIONS & pIN CONNECTIONS
APPLICATION NOTE
1) Requirement On Output Load
To ensure this module can operate efficiently and reliably, a minimum load is specified for this kind of DC/DC converter in addition to a maximum load
(namely full load). During operation, make sure the specified range of input voltage is not exceeded the minimum output load could not be 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, or use
our company’s products with a lower rated output power (A_M –W2 & B_LM-W2 Series).
2) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is to connect a selfrecovery fuse in series at the input end or add a circuit breaker to the circuit.
3)Recommended
testing and application 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).

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 recommended capacitance of its filter capacitor sees (Table 1).

It’s not recommended to connect any external capacitor in the application field with less than 0.5 watt output.
4)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 (Figure 2).

2. Max. Capacitive Load is tested at nominal input voltage and full load.
3. Unless otherwise noted, All specifications are measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load.
4. In this datasheet, all test methods are based on our corporate standards.
5. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more detail.
6. Please contact our technical support for any specific requirement.
7. Specifications of this product are subject to changes without prior notice.
