| J_N-1W Series 1W, FIXED INPUT, ISOLATED & NON-REGULATED QUAD OUTPUT,DIP PACKAGE DC-DC CONVERTER multi-country patent protection RoHS FEATURES 1KVDC Isolation DIP Package Temperature Range: -40C to +85C Internal SMD construction UL94-V0 Package No Heat sink Required No External Component Required Industry Standard Pinout RoHS Compliance PRODUCT PROGRAM Input Part Number J0505N-1W Voltage (VDC) Nominal 5 Range 4.5-5.5 Voltage (VDC)S 5 Output Current (mA) Max 50 Min 5 73 Efficiency (%, Typ) ISOLATION SPECIFICATIONS Item Test conditions Tested for 1 minute and 1mA max(Vin/Vout) Min 1000 Typ Max Units VDC APPLICATIONS J_N-1W Series is 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); 3) Where the regulation of the output voltage and the output ripple noise are not demanding. Such as: purely digital circuits, ordinary low frequency analog circuits, and IGBT power device driving circuits.

Output Voltage Regulation and Over-voltage Protection Circuit The simplest device for output voltage Ambient Temperature ( C ) regulation, over-voltage and over-current OUTLINE DIMENSIONS & PIN CONNECTIONS First Angle Projection RECOMMENDED FOOTPRINT Top view,grid:2.54*2.54mm(0.1*0.1inch), diameter:1.00mm(.039inch) protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure 2). +Vo1 Vin REG 0V1 +Vo2 0V2 +Vo3 0V3 +Vo4 0V4 1 14 4567 1110 9 8 14 1 1110 9 8 4567 GND DC DC FOOTPRINT DETAILS 4.10 (Side View) REG Vin REG +Vo1 0V1 +Vo2 0V2 +Vo3 0V3 +Vo4 0V4 Pin 1 4 5 6 7 8 9 10 11 14 Function GND 0V3 +Vo3 0V4 +Vo4 +Vo2 0V2 +Vo1 0V1 +Vin DC DC GND REG REG Note: Unit:mm(inch) Pin section:0.50*0.30mm(0.020*0.012inch) Pin section tolerances: 0.10mm( 0.004inch) General tolerances: 0.25mm( 0.010inch) (Figure 2) 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. Requirement on output load To ensure this module can operate efficiently and reliably, During operation, 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, or use our company's products with a lower rated output power. No parallel connection or plug and play. APPLICATION NOTE Recommended 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 (Figure 1). L L C L C C +Vo1 0V1 +Vo2 0V2 +V o3 0V3 +Vo4 0V4 Vin DC DC L C L GND C ( Figure 1) 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 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).
