he VA series is a family of cost effective 0.5W single output DC-DC converters. These converters achieve low cost and ultra-miniature
SIP 4 pin or DIP 8 pin size. Devices are encapsulated using flame retardant resin. The models operate from input voltage of 3.3, 5, 12,
15, 24, 48 Vdc with output voltage of 3.3, 5,7.2, 9, 12,15, 18, 24 Vdc. High performance features include 1000Vdc~3000Vdc input/output
isolation, high efficiency operation and output voltage accuracy of
±3%
maximum. Standard features include an input range of
±10%
tolerance and low output noise and ripple.
All specifications typical at Ta=25°C, nominal input voltage and full load unless otherwise specified

TEST CONFIGURATIONS
Input Reflected Ripple Current Test Step
Input reflected ripple current is measured through
a source inductor Lin(12uH) and a source capacitor
Cin(47uF, ESR<1.0Ù
at 100KHz) at nominal input and
full load.

EMI Filter
Input filter components (C1 , L , C2 , C3) are used to help
meet conducted emissions requirement for the module.
These components should be mounted as close as
possible to the module; and all leads should be minimized
to decrease radiated noise.

NOTE
1.Ripple/Noise measured with 20MHz bandwidth.
2.Tested by minimal Vin and constant resistive load.
3.Measured Input reflected ripple current with a simulated source inductance of 12uH.
4.Exceeding the absolute ratings of the unit could cause damage. It is not allowed for continuous operating.
5. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.
6 . Input filter components are be required to help meet conducted emission class B, which application refer to the EMI Filter of design &
feature configuration.
7. An external filter capacitor is required if the module has to meet IEC61000-4-4 and IEC61000-4-5.
The filter capacitor Motien suggest: Nippon - chemi - con KY series, 470uF/100V.
