PART NUMBER: VESD2-SIP
DESCRIPTION: dc-dc converter
- Miniꢀuꢀ loading
APPLICATION NOTES:
During operation, the ꢀiniꢀuꢀ output load should not be less
than 10% of the full load, and this product should never
be operated under no load. If the actual output power is very
sꢀall, please connect a resistor with proper resistance at the
output end in parallel to increase the load.
- Input filtering
To reduce the reflected ripple current and ꢀiniꢀize EMI,
especially when the converter input is ꢀore than 2” away froꢀ
the DC source, it is recoꢀꢀended to connect a low ESR
electrolytic capacitor between Vin and Gnd. The values
suggested are as shown in Table 1. If additional filtering is
required, the capacitance ꢀay be increased, or expanded to
an LC network as shown in Figure 1.
- Input Regulation
This converter accepts a narrow input range.
With a seꢀi-regulated design, the converter’s output voltage
will also change proportionally with the input voltage. To
accept a wider input range and to iꢀprove line regulation, an
input regulator can be added as shown in Fig. 2
TABLE 1

External Input Capacitance
The converter has ꢀiniꢀal protection against input over-
voltage or output over-load, and ꢀay be perꢀanently daꢀaged
if exposed to these conditions. mn input claꢀping device can
be used for input voltage liꢀiting. mn input fuse or an output
fuse also be used to protect against over-loading.

- Dual outputs used as a single output
- Output filtering
The +Vout and -Vout can be used to obtain a single output
that is the suꢀ of the two outputs. In this case, the COM pin
shouldn’t be used.
mn output capacitor is needed to ꢀeet output ripple
requireꢀents as shown in Table 2. Output capacitance ꢀay be
increased for additional filtering, but should not exeed 10 μF
or expanded to an LC network as in Figure 1.
- Output Regulation
mn external 3-terꢀinal regulator can be connected to the
output of the converter to achieve full regulation. Make sure
the converter’s output voltage provides sufficient head rooꢀ
for the regulator. mn additional benefit is that the built-in
protection features in the regulator, such as OCP, OTP, etc,
will protect the converter also. In a coꢀpliꢀentory supply, a
negative output regulator ꢀust be used to achieve the
negative regulated output.
