General Description
IB/IF-1W series built-in high efficiency LDO linear
regulator, excellent ripple index, is B/F-1W series
upgraded version, more suitable indicator of the ripple
requirements of high precision applications , for example
to the op amp power supply. IB and IF series also offers a
variety of standard voltage combinations, isolation
voltage 1.5/3.0kVdc two grades.

The DC/DC without any external filter
components in the case that can be stable and
reliable work. If you want to further reduce
ripple and improve the EMC, please connect a
external filter circuit at the inputs and outputs
(see figure). General, recommended values 10-
100uF with input capacitor, and recommended
values with output capacitor see the following

Application Note
1. Input polarity protection
The series product no positive & negative reverse polarity protection, solution is the input
series in a diode.
2. Requirement On Output Load
To ensure this module can operate efficiently and reliably, during operation, the minimum
output load is not less than 10% of the full load, and that
this product should never be
operated under no load!
If the actual output power is very small, please connect a resistor
with proper resistance at the output end in parallel to increase the load.

It’s not recommended to connect any external
capacitor in the application field with less than
0.5 watt output.
If the maximum external output capacitor still
does not meet your requirements of ripple may
be required connect the filter inductor (see
figure), Lout values recommended 4.7-100uH.
It should be noted "LC" filtering network
natural frequency should be staggered with
the DC/DC operating frequency to avoid
mutual interference.
4. On derating
When the environmental temperature exceeds
71
℃
the module must be derating use, please
refer to derating curve.

概述： 介绍一种CAN-bus网络与以太网连接，构成一个中型远程监控/数据传输网络的方法。
CAN（Controller Area Network——控制器局域网）是一种由CAN控制器组成的高性能串行数据局域通信网络，是国际上应用最广泛的现场总线之一。它最早由德国Bosch公司于1984年推出，最初用于汽车内部测量与执行部件之间的数据通信。CAN-bus总线模型符合OSI的7层结构...[详细]
