This is a 28VDC to 5VDC switching converter circuit. As a switch-mode voltage regulator, this circuit gives higher efficiency than linear regulator type. Using the National Semiconductor LM1575-5.0, this circuit can be used to convert 28VDC To 5VDC with efficiency of >80%. This circuit can be used as a 5V source @ 1A. Here is the schematic diagram of the […]

This circuit is used to connect the camera with very log wire. This is actually a video amplifiers. This circuit consist of two part, they are sender part and receiver part. At the sender part, this circuit uses an amplifier to make a stronger signal. So the signal can be transmitted through the long cables. To transmitted the signal, this […]

For driving multiple video cables, the suitable component is LT1206 because it has low output impedance, 60MHz bandwidth and 250mA output current capability. But don’t forget about unterminated line effect when driving multiple cables. A crosstalk to other lines caused by a reflected wave is propagate back to the driver because the driver output is non zero impedance. Here is […]
