Working Principle

The NCT5917W TR is a voltage-mode high-frequency switching regulator. It operates by converting the input voltage to a pulse-width modulated (PWM) signal. This signal is then used to control a MOSFET switch, which switches to either a high voltage or a low voltage depending on the duty cycle that is set. When the duty cycle is high, the output voltage is higher, and when the duty cycle is low, the output voltage is lower.

The device uses a Feedback Control System to regulate the output voltage. The Feedback Control System consists of a Comparator, Error Amplifier and Voltage Reference. The Error Amplifier compares the output voltage (Vout) to the reference voltage. If the voltage is too high, the Error Amplifier will decrease the duty cycle, resulting in a decrease in the output voltage. Similarly, if the output voltage is low, the Error Amplifier will increase the duty cycle, resulting in a higher output voltage.

The NCT5917W TR also features a wide range of features, such as temperature compensation, over-voltage and over-current protection, and soft start, which help to reduce system response time and ensure system reliability. In addition, the device offers a wide operating range, providing better system versatility.
