JCK5012S12

The JCK5012S12 series of DC-DC converters provides efficient step-down voltage conversion from an input voltage of 4.5-24 VDC to output voltage of 1.2V to 16 VDC. These features make them suitable for many applications including Industrial Equipment, Automotive, Medical, Broadcast, Office Automation and Instrumentation.

The JCK5012S12 converters are specifically designed to operate in demanding applications where space is limited. Their thin-type package can be installed on a PCB with less than 6.8 mm thickness, yet they deliver up to 7 W of continuous power output. This makes them ideal for applications with limited space, such as LCD displays, Telecom, Wind Power and Automotive applications.

The JCK5012S12 series of DC-DC converters follow a “step-down” topology, meaning the voltage is reduced from the input voltage to the desired output voltage. This is achieved by using a high frequency switching power supply, which consists of four elements: a switching circuit, a rectification circuit, an inductor and a capacitor.

The switching circuit is comprised of a transistor switch and its control circuit. It is used to turn the power supply on and off at a predetermined frequency, thus controlling the amount of energy stored and released in each cycle. The rectification circuit is made up of the diodes and it is used to convert the alternating current (AC) input into direct current (DC) output. The inductor is used to store the energy when the switch is “on”, and the capacitor is used to smooth out the output signal.

The key benefit of using a step-down topology is that it allows for higher efficiency than most other power conversion designs, making it ideal for battery powered and similar types of applications. Additionally, the JCK5012S12 offers wide input voltage range, wide output voltage range, low output noise, high temperature capability and patented current fold back technology to avoid overload.
