PART NUMBER: VWRBS2
Application Notes:
- All of the VWRBS2-SIP Series have been tested
-
R= Vc - Vd - 0.65V
Remote on/off control (see figure 1)
ON: When control pin (CTRL pin 3) open or Ic
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:
example 1 : Logic circuit — Apply 5V TTL logic signal on Vc to disable output
example 2 : Short Vin to Vc — Apply 12V on Vc to disable output
according to the following recommended testing
circuit before leaving the factory. This series should
be tested under load(Figure 1). If you want to further
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).

DESCRIPTION: dc-dc converter
- Input current
- Output Load
- NC Terminals
Nominal input voltage range. The input
current of the power supply must be sufficient
to the startup current (Ip) of the DC/DC module
(Figure 2)
In order to ensure the product operates
efficiently and reliably, make sure the specified range
of input voltage is not exceeded.
No parallel connection or plug and play.
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.;
