| AM1DR-N Series 1 watt dc-dc converters * * * * 7PIN SIP PACKAGE REGULATED OUTPUT VOLTAGE LOW RIPPLE & NOISE HIGH EFFICIENCY UP TO 79% * * * * INPUT/OUTPUT ISOLATION: 1000VDC OPERATING TEMPERATURE: -40C ... +85C PIN-COMPATIBLE WITH MULTIPLE MANUFACTURERS UL94-VO PACKAGE DC-DC CONVERTERS GENERAL DESCRIPTION Our AM1DR-N series is a family of cost effective 1W single output isolated DC-DC converters. These converters achieve low cost and ultra-miniature SIP7 pin size without compromising performance and reliability. Twelve models operates from input voltages of 5, 12 & 24VDC; producing regulated output voltage levels of 5, 9, 12, 15VDC. Full SMD-design and a 100% production test of parameters ensures a high reliability in this product.

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). 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.
