Applications: The VRB3-DIP Series are specially designed for applications where wide range input voltage 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 wide range (voltage range: 2:1); 2) Where isolation is necessary between input and output (Isolation Voltage = 1500 Vdc) 3) Where the regulation of the output voltage and the output ripple noise are demanding. These products don’t apply to: 1) Where the input voltage t is required to be more than 2:1; 2) Where the isolation voltage between input and output is required to be >1500VDC; 3) The output load’s actual power consumption is less than 1W.

(See Table 1) Requirement on Output Load To ensure this module operate efficiently and Outline Dimensions & Recommended Footprint Details reliably, a minimum load is specified for this kind of DC/DC converter in addition to a 31.80 9.45 maximum load (namely full load). During MP:10.5 operation, make sure the specified range of 2 3 input voltage is not exceeded, the minimum 0.50 9 10 11 out put load is not less than 10% Of the full 15.24 load, and that this product should never 20.30 23 22 be operated under no load!!! If the actual load is less below the specified minimum load. 1615 14 the output ripple of this type of DC/DC converter will increase drastically and at the same 2 x 2.54 2.54 time efficiency & reliability of the circuit will 22.86 4.00 decrease deeply .If the actual output power from the load in your circuit is very small. (Bottom View) (Side View) please connect a resistor with proper resistance at the output end to in parallel to Note: All Pins on a 2.54mm pitch; All Pin diameters are 0.50 mm(Tolerance:±0.10); All dimensions in mm. Application Note increase the load, or use our company’s other products with a lower rated output power. The products cannot be used in parallel. Recommended circuit All the VRB3-DIP Series have been tested according to the following rec- Table 1 ommended testing circuit before leaving factory. This series should be tested under load. Never be tested under no load (See Figure 1 & 2). If Vin you want to further decrease the input/output ripple, you can increase 5V & 12V 24V & 48V capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high.(See table 1).If you want to use the products in high EMI, please choose our metal packaged products. Input Current When it is used in unregulated power supply., be sure that the fluctuating Cin 100uF 10uF Cout (0+70°C) Cout (-40+85°C) 100uF (electrolytic capacitor) 47uF (tantalum capacitor) 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) V-Infinity, LLC, 20050 SW 112th Ave., Tualatin, OR 97062 www.v-infinity.com 1-866-372-1258
