JCJ1024S12

DC-DC converters are an essential component for many electronic systems. They are used to convert the voltage of a DC power source into another, usually lower, voltage. In this article, we will discuss the application field and working principle of the JCJ1024S12 DC-DC converter.

Application Field of JCJ1024S12

The JCJ1024S12 is a step-down DC-DC converter designed for use in a variety of applications. It is a non-isolated synchronous buck converter with a nominal input voltage of 12V and an output voltage of 0-10V with an adjustable output voltage range of +-0.2V. It has an integrated switch current limit of 2A, an efficiency of 85%, and a wide operating temperature range of -40-85°C. It is also a package-free design for easy integration. This makes the JCJ1024S12 ideal for applications such as LED lighting, industrial automation, medical equipment, and communication systems.

Working Principle of JCJ1024S12

The JCJ1024S12 is a non-isolated synchronous buck converter, meaning that the input and output are not isolated from each other. DC-DC converters work by controlling the conduction and switching states of a power switch that is connected in series with an inductor to create a voltage step-down. A control circuit monitors the output voltage via an error amplifier, and adjusts the duty cycle of the switch accordingly. The switch is either in the on-state, which will allow current flow through the inductor, or in the off-state, which will block current. The input voltage is stepped down by the inductor according to the duty cycle of the switch. This is known as a buck converter because it is stepping the voltage down.

Conclusion

The JCJ1024S12 is a non-isolated synchronous buck converter designed for use in a variety of applications. Its wide operating temperature range, adjustable output voltage, and package-free design make it an ideal choice for LED lighting, industrial automation, medical equipment, and communication systems. Using a control circuit to monitor the output voltage with an error amplifier, the switch is switched on and off according to the duty cycle to step down the input voltage.
