GENERAL DESCRIPTION
ELECTRICAL SPECIFICATIONS
All specifications valid at nominal input voltage, full load and +25C after warm-up time unless otherwise stated.
Our AM3T-N series is a family of cost effective 3W
single and dual output DC/DC converters. These
converters combine a shielded metal package in a
24-pin DIP compatible case and includes high per-
formance features such as a 1500VDC input/output
isolation voltage, continuous short circuit protection
and a tight line / load regulation. Wide range devices
operate over a 2:1 input voltage range continuously
providing a stable output voltage.
32 models operate from input voltages of 5, 12, 24 and
48VDC with output voltages of 3.3, 5, 12, 15, 5, 9,
12, 15VDC. High performance features include high
efficiency operation up to 83% and output voltage
accuracy of 1%. All models are packaged in a low
profile 31.75 x 20.32 x 9.45mm case. Operation is
specified over the full operating temperature range of
-40C to +85C with no derating required. Cooling is
by free-air convection.

APPLICATION NOTE
Recommended Circuit
All of our AM3T-N Series have been tested according to the following
recommended testing circuit before leaving our factory. This series should be
tested under load & never be tested under no load (See Figure 1).
If you want to further decrease the input/output ripple, you can increase
capacitance properly or choose capacitors with a low ESR. However, the
capacitance should not be too high.(See table 1).
Input Current
When it is used in an unregulated power supply, be sure that the fluctuating
range of the power supply and the rippled voltage do not exceed the module
standard. Input current of power supply should afford the startup current of
this kind of DC/DC module. (See figure 2)
External Capacitor
Although this series of DC/DC converters can work without an external
capacitor, it is highly recommended to use one in order to keep an optimum
performance. (See Table)
Requirement on Output Load
To ensure this module 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 out put load is not less than 10% Of
the full load, and that this product should never be operated under no load!!!
If the actual load is less below the specified minimum load, the output ripple
of this type of DC/DC converter will increase drastically and at the same time
efficiency & reliability of the circuit will decrease deeply .If the actual output
power from the load in your circuit 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 other products with a lower rated output power.
