DC-DC converters are devices that transform power from one voltage level to another. CQS48120-14-N is a non-isolated buck converter with an output current of up to 14A, voltage of 14V, and a range of output power from 0.7 to 11W. It is designed for a wide range of applications, from low-power industrial devices to consumer electronics and automotive systems. The CQS48120-14-N provides excellent line and load regulation, regardless of input voltage or load current. It is also designed for high efficiency, allowing it to deliver more power with less heat. Additionally, the CQS48120-14-N is covered by Korg-i’s five-year warranty for additional reliability and peace of mind.

The working principle of the CQS48120-14-N is based on a buck topology, which consists of a power switch, an inductor, and a diode. When the power switch is on, the inductor acts as an energy storage, storing energy from the input voltage while the diode prevents the current from flowing back to the input. When the switch is off, the energy stored by the inductor is released through the diode and delivers a lower output voltage. The duty cycle of the power switch controls the output voltage - the higher the duty cycle, the higher the output voltage.

The CQS48120-14-N also features a built-in current limit protection, which prevents the output current from exceeding the rated current limit in case of overload or short circuit. Besides, the device has an overvoltage protection shutdown that shuts down the regulator when the output voltage exceeds the adjustable OVP threshold. Finally, the CQS48120-14-N is designed to operate in temperatures ranging from -40 to +85°C, making it suitable for use in even the harshest environments.

CQS48120-14-N is an ideal DC-DC converter for low power applications due to its high efficiency, wide input voltage range, and wide operating temperature range. The small size and low cost make it suitable for applications such as LCD displays, portable devices, and motor control. Its overvoltage protection and current limit protection make it safe to use in industrial control systems. In addition, its five-year warranty ensures long-term reliability.
