he VB series is a family of cost effective 2W single & dual output DC-DC converters. These converters combine non-conductive black
plastic case in a 8-pin SIL / 16-pin DIL package with high performance features such as 1000Vdc~3000Vdc input/output isolation
voltage, continuous short circuit protection with automatic restart and hight line / load regulation. Devices are encapsulated using flame
retardant resin. Input voltages of 5,12,24 and 48 with output voltage of 3.3, 5,9, 12, 15, 24,
±3.3, ±5, ±9, ±12, ±15, ±24
Vdc. High
performance features include high efficiency operation up to 80% and output voltage accuracy of
±2%
maximum.
All specifications typical at Ta=25°C, nominal input voltage and full load unless otherwise specified

Maximum value at nominal input voltage and full load.
Typical value at nominal input voltage and full load.
25% minimum loading is needed.
One load is 25% to 100% load, the other load is 100% load, the output voltage variable rate is within
±5%.
Ripple/Noise measured with 20MHz bandwidth.
Test by nominal input voltage and constant resistor load.
Measured Input reflected ripple current with a simulated source inductance of 12uH.
Exceeding the absolute ratings of the unit could cause damage. It is not allowed for continuous operating.
9. Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.
10. It’s necessary to add minimum capacitor in output for some models, please check single model datasheet for detail value.

12. Input filter components are be required to help meet conducted
emission class A, which application refer to the EMI Filter of design & test configuration.
13. An external filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5.
The filter capacitor Motien suggest: Nippon - chemi - con KY series, 220uF/100V.
TEST CONFIGURATIONS
NOTE
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.
Output Ripple & Noise Measurement Test
The Scope measurement bandwidth is 20MHz.

Input filter components (C1, L) 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.
