Typical Characteristics
Recommended circuit
It is best to test with full load and not to test
without load. To further reduce output ripple,
you may increase the external capacitor,
choose a capacitor with low ESR, or add
external inductor to the circuit as shown on
the left.

PART NUMBER: VWRAS2 series
DESCRIPTION: dc/dc converter
- Input current
Application Notes:
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)
- All of the VWRAS2-SIP Series have been tested
according to the following recommended testing
circuit before leaving the factory. This series should
be tested under load(Figure 3). 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).

In order to ensure the product operates
efficiently and reliably, make sure the specified range
of input voltage is not exceeded.

- 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:
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)
R=
example 1 : Logic circuit — Apply 5V TTL logic signal on Vc to disable output
5V - 0.7V - 0.65V
Choose 720Ω resistor
R=
= 730 Ω
.005A
example 2 : Short Vin to Vc — Apply 12V on Vc to disable output
12V - 0.7V - 0.65V
R=
= 2130 Ω
Choose 2KΩ resistor
