| AM1N-N Series 1 watt dc-dc converters * * * * 24-PIN DIP PACKAGE LOW PROFILE PLASTIC PACKAGE HIGH EFFICIENCY UP TO 81% UL94-VO PACKAGE * * * INPUT/OUTPUT ISOLATION: 6000VDC OPERATING TEMPERATURE: -40C ... +85C PIN-COMPATIBLE WITH MULTIPLE MANUFACTURERS DC-DC CONVERTERS GENERAL DESCRIPTION Our AM1N-N series is a family of cost effective 1W single and dual output DC-DC converters. These converters combine plastic package in a 24-pin DIP compatible case with high performance feature such as 6000VDC input/output isolation voltage. Twenty four models operate from input voltages of 5, 12 & 24VDC with output voltages of 5, 9, 12, 15, 5, 9, 12, 15VDC. Operation is specified over the full operating temperature range of -40C to +85C with no derating required. Cooling is by free-air convection.

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 the external capacitor table. To get an extremely low ripple, an "LC" filtering 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" filtering network should be staggered with the dc/dc frequency to avoid mutual interference (see figure 1). DC-DC CONVERTERS 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. For single output 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. 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 2).
