It is suitable for various low power dissipation applications including: voltage regulation, charging, switching, power conversion, and other related tasks. It also supports various power requirements such as 5 V/3.3 V, and 12 VDC output.

The device is also suitable for applications that require high power efficiency such as notebook and netbook designs. It is particularly suitable for wireless power applications with its high efficiency, flexible input voltage range, low stand-by power and wide output power range.

Working Principle

The JCK3012D15 DC to DC converter utilizes a forward converter topology for power conversion. It employs a high-frequency power switch to convert input voltage to a desired output voltage. This architecture offers high power conversion efficiency including low stand-by power consumption and low component costs.

The power switch is driven by a Pulse Width Modulator (PWM) control circuit. The PWM controller drives a power stage, typically consisting of a MOSFET switch, an inductor and a diode, to generate a regulated voltage output. The power switch is controlled by an external voltage reference. The controller modulates the width of the pulses in order to maintain the desired output voltage according to the voltage reference. Due to its forward power conversion topology, the JCK3012D15 supports input voltages up to 24 VDC and is capable of driving up to 200mA of load current.

For improved performance, the JCK3012D15 includes a Voltage Mode feedback with 40KHz switching frequency. This enables faster transient response and better load regulation. To ensure it meets the industry standards, the device complies with RoHS (Restriction of Hazardous Substances) and is UL/cUL certified.

Its output voltage is fixed and is adjusted by using an external resistor divider network. The device is also capable of generating multiple output voltage configurations including same polarity dual output, dual output with different polarity, and single output.

Conclusion

The JCK3012D15 DC to DC converter is a popular device for low power dissipation applications. It provides a reliable and high-efficiency solution for various applications, such as voltage regulation, charging, switching, and power conversion. Due to its forward power conversion topology, it is particularly suitable for high power efficiency applications. It is RoHS and UL certified for quality assurance.
