The KC-15/12VDC is an integrated circuit designed for small power system applications, such as home lighting, security systems and telecommunication equipment. It is a highly efficient DC-DC converter that provides an output voltage of 12V. It is designed to operate with a wide input voltage range and can provide a maximum output current of up to 15 amps.

The KC-15/12VDC is available in a range of packaging options, including TO-220, TO-252, and SOT-223. The DC-DC converter has an internal current limiting protection, over-voltage protection, short circuit protection, and under-voltage protection. In addition, the chip features EMI interference filter circuitry, on-off delay circuit and a power indicator.

The KC-15/12VDC is typically used in applications such as industrial, automotive and consumer electronics where reliable, long life, high efficiency and low cost operation are required. It is an easy-to-use and cost effective solution for powering a range of electronic devices such as mobile phones, computers, tablets, etc. It is also used for powering consumer electronic appliances such as TV’s, DVD players, game consoles, and more.

The working principle of the KC-15/12VDC is as follows. It is based on the buck converter topology, which allows the chip to reduce a high input voltage to an accurate and proportional output voltage. By controlling the pulse width modulation (PWM) of the switching transistors, the current is drawn from the input capacitor in such a way that the output voltage is regulated. The chip also features a start-up circuit, which allows for soft start operation and thus providing transient protection.

The circuit is also protected against reverse-voltage, over-current, over-temperature and short-circuit conditions. The over-voltage protection circuitry of the chip is based on sensing the output voltage level and disconnecting the input source if it exceeds the over-voltage threshold.

The integrated circuit also includes an adjustable frequency control in order to optimize the power efficiency. The chip also includes current-mode control technology, which provides superior line and load regulation performance. The chip also provides a power good signal, which allows the system to monitor the DC-DC converter.

Finally, the chip has built-in thermal protection that will shut it down if the device gets too hot. Additionally, the chip has adjustable soft-start and under-voltage lockout features, which prevent unexpected startup and operation of the DC-DC converter. Because of its wide input voltage range and current capacity, the KC-15/12VDC is an ideal solution for small, low-power applications. It is a reliable solution for applications where high efficiency and cost-effective operation are needed.
