APPLICATIONS The D-NXT 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); ISOLATION SPECIFICATIONS 3) Where the regulation of the output voltage Item Test Conditions and the output ripple and noise are not demanding. Tested for 1 minute and 1mA max Such as:purely digital circuits , ordinary low Isolation voltage(Vin/Vout) frequency analog circuits and IGBT power device Isolation voltage(Vo1/Vo2) Tested for 1 minute and 1mA max driven circuits, etc. MICRODC R ESERVES THE COPYRIGHT http://www.microdc.cn 15 Short circuit protection* ⑦ D 05 05 05 N X T ①Product Series ③The 1st Output Voltage ⑤No Pin ⑦SMD Package 25 Min.

RECOMMENDED CIRCUIT RECOMMENDED REFLOW SOLDERING PROFILE Remark: The curve applies only to the hot air reflow soldering TYPICAL CHARECTERISTICS EXTERNAL CAPACITOR TABLE (TABLE 1) 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 products with a lower rated output power (D-NXT -W2/W5). 2) Recommended testing 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 (Figure1). 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 It's not recommended to connect any external capacitor in the application field with less than 0.5 watt output. 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 (Table 1). 3) 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 (Figure2). 4) Overload Protection Under normal operating conditions , the output circuit of these products has no protection against overload . The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit. 5) Cannot use in parallel and hot swap http://www.microdc.cn Technical Enquiries-Email:[email protected] Tel:0086-20-86000646 Page 2 of 3 D-NXT Series OUTLINE DIMENSIONS& RECOMMENDED FOOTPRINT MECHANICAL DIMENSIONS RECOMMENDED FOOTPRINT Note: Unit: mm[inch] Pin section tolerances: ± 0.10mm[ 0.004inch] General tolerances: ± 0.25mm[ 0.010inch] TUBE OUTLINE DIMENSIONS REEL PACKING OUTLINE DIMENSIONS Note: Unit: mm[inch] General tolerances:±0.50mm[± 0.020inch] L=530mm[20.866inch] Devices per tube quantity: 28pcs L=220mm[8.661inch] Devices per tube quantity: 10pcs Short tube inner package dimensions : L*W*H= 255*170*80mm Short tube outer package dimensions(with six inner package boxes): L*W*H= 375*280*270mm Long tube inner package dimensions : L*W*H= 580*200*100mm Long tube outer package dimensions(with two inner package boxes): L*W*H= 600*215*220mm Long tube outer package dimensions(with three inner package boxes): L*W*H= 600*215*325mm Note: Unit :mm[inch] General tolerances: ±0.50mm[ 0.020inch] Per reel of packing quantity:400pcs Inner package carton dimensions: L*W*H=365*350*105mm Tube Quantity : 800pcs Outer package carton dimensions: L*W*H=390*360*245mm Tube Quantity:1600pcs RoHS COMPLIANT INFORMATION Microdc Professional Power Module,Inc.
