Applications

NCP6361BGEVB is suitable for a wide range of applications, such as cameras, PDAs, portable medical equipment, hard drives, and other consumer electronic products. It can also be used in many industrial or automotive applications with multiple supply voltages.Examples include motor control, digital displays, or power supplies.

Working Principle

The NCP6361BGEVB is based on an advanced monolithic switch mode buck converter topology. This topology offers an efficient, cost-effective solution for converting a wide range of input voltages to an adjustable output voltage. The converter includes an internal high-frequency oscillator which delivers Pulse-Width Modulation (PWM) operation at a frequency up to 500 kHz. The oscillator operates at a fixed frequency and is independent of the output voltage. This ensures constant switching times regardless of output voltage. The output voltage can be adjusted using the Control and Feedback pins. The external resistors can be used to set the output voltage. The output voltage is regulated by monitoring the feedback voltage that is created by the resistors connected to the Control and Feedback pins.

This converter is also integrated with features such as thermal shutdown, frequency foldback and soft start. The thermal shutdown feature helps to protect the NCP6361BGEVB from overexposure to high temperatures. The frequency foldback feature limits the rate of switch frequency when the IC nears thermal limiting, allowing the IC to remain in operation for longer periods of time. The soft start feature is used to reduce the inrush current associated with the startup of the IC. This ensures that the circuit does not draw excessive current upon startup.
