Working Principles

The NCP1203D60R2G operates on the principle of pulse width modulation (PWM) control. It regulates the output voltage by adjusting the duty cycle of the switching signal. The integrated circuit uses a power MOSFET to switch the input voltage at a high frequency, resulting in efficient power conversion.

During operation, the feedback pin (FB) monitors the output voltage and adjusts the duty cycle accordingly. The compensation pin (COMP) ensures stability by compensating for any variations in the feedback loop. The current sense pin (CS) detects overcurrent conditions and triggers the overcurrent protection mechanism.

The NCP1203D60R2G also incorporates various protection features such as overvoltage protection, soft-start function, and thermal shutdown. These features enhance the reliability and safety of the power management system.
