The input - All of the VWRBS2-SIP Series have been tested current of the power supply must be sufficient according to the following recommended testing to the startup current (Ip) of the DC/DC module circuit before leaving the factory. This series should (Figure 2) be tested under load(Figure 1). If you want to further Input Current(A) decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance should not be too high(Table 2).

Temperature Derating Graph - NC Terminals Unless otherwise specified, NC terminals of all series are used for converter's interior circuit connection, and are not allowed connection of any external circuit.; Operating Temp.( C ) - Remote on/off control (see figure 1) ON: When control pin (CTRL pin 3) open or Ic < 0.5mA, converter will have normal output. OFF: With a 3-10mA input current (Ic) to pin 3, output will be disabled. Under no conditions should input current (Ic) exceed 20mA. The Value of R in Figure 1 can be derived as follows: R= Vc - Vd - 0.65V Ic Vc= Voltage at control input Vd= Diode (D1) voltage drop (.7V voltage drop typical ) Ic= Input Current (5mA recommended disable current) example 1 : Logic circuit — Apply 5V TTL logic signal on Vc to disable output R= 5V - 0.7V - 0.65V = 730 Ω .005A Choose 720Ω resistor example 2 : Short Vin to Vc — Apply 12V on Vc to disable output R= 12V - 0.7V - 0.65V = 2130 Ω .005A Choose 2K Ω resistor 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 www.v-infinity.com
