GENERAL DESCRIPTION

Our AM1/4L-N series is a family of cost effective

1/4W single and dual output DC/DC converters.

These converters combine a miniature SMD pack-

age and high performance features such as a 1000 &

3000VDC input/output isolation voltages, continu-

ous short circuit protection and a tight line / load

regulation.

96 models operate from input voltages of 3.3, 5, 12 and

24VDC producing output voltages of 3.3, 5, 9, 12, 15,

24, ±5, ±9, ±12, ±15 & ±24VDC. Full SMD design

and a 100% production test of parameters ensures a

high reliability in this product.

TYPICAL CHARACTERISTICS

SINGLE OUTPUT MODELS

APPLICATION NOTE

General Application

In regular circuits, our company’s DC/DC converters may be used directly without any peripheral components (see Figure

2). The basic input/output isolation may be used to provide a group of simple isolated polar output power supplies or to

generate power supply lines of different voltages.

Voltage And Polarity Inversion

A key performance of this DC/DC converter is high electric isolation capability. Thus, only one DC/DC converter may allow

for several potential differences in the layout of circuit board. If necessary, you may connect the output end of the positive

to input ground, then the negative output end will generate a negative voltage (see Figure 1).

Filtering

DUAL OUTPUT MODELS

In some circuits which are sensitive to noise and ripple, a filtering capacitor may be added to the DC/DC output end and

input end to reduce the noise and ripple. 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 filtering capacitor sees the External Capacitor Table. To get an extremely low

ripple, a “LC” filter network may be connected to the input and output ends of the DC/DC converter, which may produce

a more significant filtering effect. It should also be noted that the inductance and the frequency of the “LC” filter network

should be staggered with the DC/DC frequency to avoid mutual interference (see Figure 3).

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 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.

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

circuits.

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 stabilizer with

overheat protection that is connected to the input or output end in series (see Figure 4).

Product Reliability

The MTBF is the mean time between failures under full load. If the actual load is less than 20% of the rated load or greater

than the rated load, then this productís reliability will be greatly reduced.

Input Polarity Protection

Under normal conditions, this productís input circuit has no protection against polarity inversion; the solution is to connect

a diode in series at the input.
